Feature/sliding freq (#3280)
* 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 Co-authored-by: gullradriel <gullradriel@users.noreply.github.com>
