v2.1.0: Upgrade esp-wifi-connect to 3.0; New device state machine (#1528)

* Upgrade component version

* update fonts component version

* Handle OTA error code

* Update project version to 2.1.0 and add device state machine implementation

- Upgrade  esp-wifi-connect to 3.0.0, allowing reconfiguring wifi without rebooting
- Introduce device state machine with state change notification in new files
- Remove obsolete device state event files
- Update application logic to utilize new state machine
- Minor adjustments in various board implementations for state handling

* fix compile errors

* Refactor power saving mode implementation to use PowerSaveLevel enumeration

- Updated Application class to replace SetPowerSaveMode with SetPowerSaveLevel, allowing for LOW_POWER and PERFORMANCE settings.
- Modified various board implementations to align with the new power save level structure.
- Ensured consistent handling of power save levels across different board files, enhancing code maintainability and clarity.

* Refactor power save level checks across multiple board implementations

- Updated the condition for power save level checks in various board files to ensure that the power save timer only wakes up when the level is not set to LOW_POWER.
- Improved consistency in handling power save levels, enhancing code clarity and maintainability.

* Refactor EnterWifiConfigMode calls in board implementations

- Updated calls to EnterWifiConfigMode to use the appropriate instance reference (self or board) across multiple board files.
- Improved code consistency and clarity in handling device state during WiFi configuration mode entry.

* Add cellular modem event handling and improve network status updates

- Introduced new network events for cellular modem operations, including detecting, registration errors, and timeouts.
- Enhanced the Application class to handle different network states and update the display status accordingly.
- Refactored Ml307Board to implement a callback mechanism for network events, improving modularity and responsiveness.
- Updated dual_network_board and board headers to support new network event callbacks, ensuring consistent handling across board implementations.

* update esp-wifi-connect version

* Update WiFi configuration tool messages across multiple board implementations to clarify user actions
