Kaj SchittecatandClaude Opus 4.8 bcc084820c touch: radio presets set a REAL duty limit — airtime factor was 10x off (#161)
MeshCore's airtime_factor is the Dispatcher's TX pacing multiplier: duty =
1/(1+af), so a 10% duty limit needs af = 9. The presets wrote af = pct/100
(0.10), which configured every preset user's radio to ~91% duty -- the Home
meter's 'always 91%' was truthfully reporting the misconfiguration, on every
region preset including UK/EU.

- applyMeshRadioPresetFields converts duty% -> factor correctly (clamped to
  the core's 0..9).
- findMatchingMeshRadioPreset accepts both the correct and the old buggy value
  so previously-configured devices still show their preset in the dropdown.
- healPresetAirtimeFactor (run once at UI begin) rewrites the factor for
  devices whose params exactly match a preset and whose stored factor matches
  the OLD buggy write -- the exact-match requirement is the guard against
  touching deliberate user-set values.

NOTE for the web client: Meshcomod-client/shared/radio_presets.ts documents
the same pct/100 convention and needs the matching fix.
