Airband VOR receiver and trasmitter (#3244)

* First test

* Reorder includes for consistency and fix string dereference in VorCdiIndicator

* Add memory section and linker script entry for vor_rx application

* Testing VOR TX

* Moving VOR TX to SD

* Code refactoring to align with guidelines

* Add TODO comment to verify radial sign convention in vor_tx_config

* Remove unnecessary set_dirty() calls in VorRxView methods

* Update Course Deviation Indicator label and adjust UI element positions

* Update VorTxView to run prepared image from memory map

* Update build condition in nightly release workflow to include workflow_dispatch event

* Reverting action changes

* Adjust Course Deviation Indicator layout and refine painting logic

* Refactor VorRxView UI elements for improved layout and clarity

* Add calibration field and update radial calculation logic in VorRxView

* Enhance VOR processing: add renormalization to phase oscillator, improve signal handling, and update configuration parameters

* Implement radial smoothing and TO/FROM state handling in VorRxView; update VOR processing logic

* Setting comments inline

* Refactor VorCdiIndicator and VorRxView: change normalize_signed_degrees to use int32_t, update radial smoothing to use fixed point arithmetic to reduce flash usage

* Update external app address end to 0xAE0B0000

* Update set_vor_tx_config to include enabled parameter for consistency

* Refactor VorRx to omit decim_2 stage and update comments for clarity on VOR processing

* Add RSSI, Channel, and Audio fields to VorRxView to mimic existing apps

* Refactor VorRxView labels and status messages

* Update VorRxView calibration field range to allow full circle input

* Completing Ident transmission logic

* Fixing TX gain and moving log label

* Refactor VOR phase calculations and update radial offset handling for accurate bearing representation

* Add low-pass filters to strip 9960 Hz subcarrier from audio output
