Add San Morse 1.0

[sanjorgek]

Application Submission

San Morse 1.0 — a Morse code trainer designed for learning while you write, instead of requiring you to know the codes beforehand.

• Interactive Morse decision tree on screen; the OK button works as a telegraph key (quick release = dot, hold = dash), with pause-based letter commit and a visible countdown. Numbers and signs live on level 5 of the tree, with automatic zoom.
• Text to Morse: type a text and play it back with sound, LED and vibration, highlighting the current character/symbol, with live adjustable speed.
• English / Spanish interface.
• Persistent settings: language, volume, tone, vibration, LED, WPM speed and key timings.

Extra Requirements

None — uses only the built-in speaker, LED, vibration and SD card (settings file).

Author Checklist (Fill this out)

• I've read the contribution guidelines and my PR follows them
• I own the code I'm submitting or have code owner's permission to submit it
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have validated the manifest file(s) with python3 tools/bundle.py --nolint applications/CATEGORY/APPID/manifest.yml bundle.zip

AI usage disclosure (Fill this out):

• Partially AI assisted (clarify below which code was AI assisted and briefly explain what it does).

• Fully AI generated (explain what all the generated code does in moderate detail).

• The app was written with Claude Code under my direction and tested on real hardware (Flipper Zero, official firmware 1.4.3). The code consists of: a Morse lookup table and the dichotomic tree stored as a binary-heap array (morse.c); a custom View that renders the tree with windowed zoom and handles OK press/release timing as a telegraph key, with a 50 ms timer for pause-based letter/space commit (san_morse.c); a playback worker thread that converts text to dot/dash timings (PARIS standard) and drives speaker/LED/vibration (player.c); persistent settings stored as a versioned blob on the SD card (settings.c); and a static string table for the English/Spanish UI (i18n.c). The manifest was validated with tools/bundle.py including the full lint/build step.
