Feature/sliding freq (#3280)

Browse Source 
* Add sliding-frequency audio receiver tuning
* Move ADS-B receiver to external app
* Move AIS receiver to external app
* Move APRS receiver to external app
* Move APRS transmitter to external app
* Isolate filtered spectrum collection from WFM
* Fixed the issues #3280
* fpga_bridge.c: init registers per reference fpga_init, add quarter-shift mode setter
* radio.hpp: expose cached FPGA quarter-rate shift
* radio.cpp: program FPGA quarter-rate shift together with tuning offset
* tuning.hpp: pass AFE rate and direction to tuning config, add quarter_shift field
* tuning.cpp: import full PRALINE RX/TX tuning tables with quarter-shift offsets
* clock_manager: stop writing bogus RX digital gain, keep quarter shift across rate changes
* receiver_model: port LPF bandwidth from reference auto_bandwidth, use cached quarter shift
* adsb_rx: enable RF amp by default on first run
* ui_geomap.hpp: add hemisphere fields, degrees become magnitude
* ui_geomap: use hemisphere selector for lat/lon sign, fix minute/second wrap carry
* ui_menu: guard select against empty menu
* waterfall_designer: header updates for profile file handling
* waterfall_designer: exception-free profile parsing, CRLF handling, deferred nav callbacks, backup cleanup
* external.ld: scope app section globs to their own object directories
* CMakeLists: relink when external.ld changes
* tools: add external app symbol placement checker
* tools: add guru meditation address lookup script
* tools: add per-function stack usage report script
