Fix and optimize tilt test case issues

Tilt tests started to fail after the latest changes. Had to make
some fixes and optimizations so that the test code resets the
tilt controls correctly and aligns with relay_chn's timing requirements.

Fixes #1115

 - Tilt sensitivity

+### NVS Operation Details
+When NVS storage is enabled (CONFIG_RELAY_CHN_ENABLE_NVS=y), the component creates a dedicated background task to manage all NVS write operations. This design has important implications for how you use the NVS-related functions:
+- **Asynchronous Writes:** All `set` operations (e.g., `relay_chn_flip_direction()`, `relay_chn_set_run_limit()`) are asynchronous. They add the write request to a queue and return immediately, preventing the calling task from being blocked.
+- **Synchronous Reads:** All get operations (e.g., `relay_chn_get_direction()`) are synchronous. They read the value directly from the NVS storage and will block the calling task until the read is complete.
+- **Batched Commits:** To optimize performance and minimize flash wear, the NVS task uses a batching mechanism for writes. It collects multiple write requests and commits them to the NVS flash in a single operation after a short period of inactivity (typically 200ms).
+
+> [!IMPORTANT]
+> Due to the asynchronous and batched nature of write operations, a call to a get function may not immediately reflect a value that was just written by a set function. Your application should account for this small delay.

+# Relay Channel Multi Example
+
+## Introduction
+
+This example demonstrates how to use the relay channel component to control a 3-channel setup with button inputs and LED status indication. It showcases:
+
+- Basic relay channel operations (forward/reverse running, stopping)
+- Secondary operations (tilting, direction flipping)
+- State change event handling with a listener
+- Relay channel run limit
+- Button event handling using esp-iot-solution's button component
+- Visual feedback using esp-iot-solution's LED indicator component
+
+## How to Use Example
+
+This example has been tested on an `ESP32-C3-DevKitM-1U` board. However, it can be adapted to any ESP32-based board with at least six available GPIO pins by adjusting the configuration options.
+
+### Hardware Required
+
+* An ESP32-based development board
+* 2 relays connected to GPIO pins (default: GPIO4, GPIO5)
+* 3 buttons connected to GPIO pins:
+  - UP button (default: GPIO0)
+  - DOWN button (default: GPIO1) 
+  - STOP button (default: GPIO2)
+  - SELECT button (default: GPIO3)
+* LED indicators for status indication of each channel (default: GPIO4, GPIO10 and GPIO9 respectively)
+
+#### Hardware Schematic
+
+Relay blocks are ommitted for simplicity. You can refer to schematic of the [Single-channel example](/examples/relay_chn_single/README.md) for a fully implemented relay block.
+
+> [!NOTE]
+> A single relay channel consists of two relay block and two GPIO pins.
+
+![Hardware Schematic](example_schematic.png)
+
+### Configuration
+
+The example can be configured through `menuconfig` under "Relay Channel Multi Example Configuration":
+
+1. Button active level (`EXAMPLE_RLCHN_BTN_ACTIVE_LEVEL`)
+   - Select between active LOW or HIGH logic level for buttons
+   
+2. GPIO assignments:
+   - UP button pin (`EXAMPLE_RLCHN_BTN_UP_IO_NUM`, default: 0)
+   - DOWN button pin (`EXAMPLE_RLCHN_BTN_DOWN_IO_NUM`, default: 1)
+   - STOP button pin (`EXAMPLE_RLCHN_BTN_STOP_IO_NUM`, default: 2)
+   - SELECT button pin (`EXAMPLE_RLCHN_BTN_SELECT_IO_NUM`, default: 3)
+   - LED indicator pin (`EXAMPLE_RLCHN_LED_INDICATOR1_IO_NUM`, default: 4)
+   - LED indicator pin (`EXAMPLE_RLCHN_LED_INDICATOR2_IO_NUM`, default: 10)
+   - LED indicator pin (`EXAMPLE_RLCHN_LED_INDICATOR3_IO_NUM`, default: 9)
+
+3. Long press timing:
+   - `EXAMPLE_RLCHN_BTN_LONG_PRESS_TIME_MS`: Duration for long press actions (1500-3000ms, default: 2000ms)
+
+### Button Operations
+
+The example uses esp-iot-solution's `button` component to handle the following operations:
+
+- **UP button**:
+  * Short press: Start forward movement
+  * Long press: Start forward tilt (stops on release)
+
+- **DOWN button**: 
+  * Short press: Start reverse movement
+  * Long press: Start reverse tilt (stops on release)
+
+- **STOP button**:
+  * Short press: Stop movement
+  * Long press: Flip movement direction
+
+- **SELECT button**:
+  * Short press: Selects a channel to operate
+  * Long press: Selects all channels to operate in batch
+
+### LED Indicator States
+
+The example uses esp-iot-solution's `led_indicator` component to show different states:
+
+- **Running**: LED blinks at 300ms on, 100ms off
+- **Tilting**: Fast blink at 100ms on, 50ms off
+- **Operation Success**: Two quick blinks
+- **Operation Fail**: One long blink
+
+### Dependencies
+
+This example requires:
+- ESP-IDF v4.1 or later
+- esp-iot-solution components:
+  * button v4.1.1 or later
+  * led_indicator v1.1.1 or later
+- relay_chn component
+
+## Example Output
+
+When the application boots, it will wait for a button event. Then ta state listener will print state changes.

+# Relay Channel Single Example
+
+## Introduction
+
+This example demonstrates how to use the relay channel component to control a 2-relay setup with button inputs and LED status indication. It showcases:
+
+- Basic relay channel operations (forward/reverse running, stopping)
+- Secondary operations (tilting, direction flipping)
+- State change event handling with multiple listeners
+- Relay channel run limit
+- Button event handling using esp-iot-solution's button component
+- Visual feedback using esp-iot-solution's LED indicator component
+
+## How to Use Example
+
+This example has been tested on an `ESP32-C3-DevKitM-1U` board. However, it can be adapted to any ESP32-based board with at least six available GPIO pins by adjusting the configuration options.
+
+### Hardware Required
+
+* An ESP32-based development board
+* 2 relays connected to GPIO pins (default: GPIO4, GPIO5)
+* 3 buttons connected to GPIO pins:
+  - UP button (default: GPIO0)
+  - DOWN button (default: GPIO1) 
+  - STOP button (default: GPIO2)
+* 1 LED for status indication (default: GPIO3)
+
+#### Hardware Schematic
+
+![Hardware Schematic](example_schematic.png)
+
+### Configuration
+
+The example can be configured through `menuconfig` under "Relay Channel Single Example Configuration":
+
+1. Button active level (`EXAMPLE_RLCHN_BTN_ACTIVE_LEVEL`)
+   - Select between active LOW or HIGH logic level for buttons
+   
+2. GPIO assignments:
+   - UP button pin (`EXAMPLE_RLCHN_BTN_UP_IO_NUM`, default: 0)
+   - DOWN button pin (`EXAMPLE_RLCHN_BTN_DOWN_IO_NUM`, default: 1)
+   - STOP button pin (`EXAMPLE_RLCHN_BTN_STOP_IO_NUM`, default: 2)
+   - LED indicator pin (`EXAMPLE_RLCHN_LED_INDICATOR_IO_NUM`, default: 3)
+
+3. Long press timing:
+   - `EXAMPLE_RLCHN_BTN_LONG_PRESS_TIME_MS`: Duration for long press actions (1500-3000ms, default: 2000ms)
+
+### Button Operations
+
+The example uses esp-iot-solution's `button` component to handle the following operations:
+
+- **UP button**:
+  * Short press: Start forward movement
+  * Long press: Start forward tilt (stops on release)
+
+- **DOWN button**: 
+  * Short press: Start reverse movement
+  * Long press: Start reverse tilt (stops on release)
+
+- **STOP button**:
+  * Short press: Stop movement
+  * Long press: Flip movement direction
+
+### LED Indicator States
+
+The example uses esp-iot-solution's `led_indicator` component to show different states:
+
+- **Running**: LED blinks at 300ms on, 100ms off
+- **Tilting**: Fast blink at 100ms on, 50ms off
+- **Operation Success**: Two quick blinks
+- **Operation Fail**: One long blink
+
+### Dependencies
+
+This example requires:
+- ESP-IDF v4.1 or later
+- esp-iot-solution components:
+  * button v4.1.1 or later
+  * led_indicator v1.1.1 or later
+- relay_chn component
+
+## Example Output
+When the application boots, it will wait for a button event. Then the two state listeners will print state changes.
