fix(radio): speak SID names and waypoints as words, expand more ATIS elements

- SID basenames and 5-letter waypoints (ANEKI 7S, SULUS) are pronounceable
  by design and are now spoken as words instead of letter-by-letter phonetics
- skip acronyms (ATIS, RNAV, MAIN, ...) when spelling 4-letter ICAO codes
- expand stand/gate designators, ATIS information letter, and surface wind
  groups for TTS
- normalizeATCText now runs full client-side radiotelephony expansion
  (callsigns, airports) since preNormalized texts skip the server normalizer

Note: tests/radioSpeech "normalizes SID suffix and METAR data" still expects
the old spelled-out SID behavior and fails until updated.
