agessaman f79d22c810 fix: resolve remaining upstream-merge build breaks; park oversize TLora
Three real regressions from the 2026-07-19 upstream merge, all invisible to the
two prescribed smoke builds:

- heltec_tracker_v2/HeltecTrackerV2Board.cpp: the FEM trio
  (setLoRaFemLnaEnabled/canControlLoRaFemLna/isLoRaFemLnaEnabled) was duplicated
  verbatim by auto-merge, and upstream's new powerOff() (35f654ce) used
  P_LORA_PA_POWER unguarded — a macro defined only for the tracker_v2 envs, while
  heltec_tracker_v1_1 compiles the same board file. Guarded it the same way
  LoRaFEMControl.cpp already guards that macro.

- SimpleMeshTables.h: the tracker variants pull in TFT_eSPI, whose
  TFT_eSPI_ESP32_S3.h defines FS_NO_GLOBALS. That suppresses FS.h's own
  'using fs::File', so File never reached global scope and every TU routed
  through it failed with "'File' has not been declared" — here and at
  simple_repeater/MyMesh.h:158. Restore the using when FS_NO_GLOBALS is set.
  Explicit fs::File is not an option: File is also the global type on the
  nRF52/RP2040 paths, which have no fs namespace.

- ST7735Display.cpp: upstream's HSPI fix (d30d8ed7) guarded on
  HELTEC_LORA_V3 || HELTEC_TRACKER_V2. heltec_tracker_v1_1 matches neither and
  fell through to &SPI1, which is not instantiated on ESP32. Added it to the guard.

Also parks LilyGo_TLora_V2_1_1_6_{repeater,room_server}_observer_mqtt with a
trailing underscore (the nibble_screen_connect convention from b8f1fad6), which
also excludes them from the workflows' enumeration regex. That board does NOT
fit and never did: 2,069,397 / 1,966,080 = 105.3% on flex, with no webconfig and
no upstream merge. It has been failing on production all along — the release
ships 30 envs, not 32 — hidden because build.sh does not propagate pio's exit
code. Dropping webconfig would recover ~46 KB of a ~101 KB deficit, so that is
not a fix. Rationale and options in .scratch/tlora-v2-oversize.md.
