This PR adds an Azerbaijani (az) translation.

New file locale/az.yml: 166 strings, all filled in.
locale/lv_i18n.c and locale/lv_i18n.h are not regenerated in this PR.
The bundled Montserrat fonts do not include U+0259 (ə), a letter Azerbaijani uses in 74 of these strings.

Summary by CodeRabbit

  • New Features

    • Added Azerbaijani language support across the device interface, including settings, tools, status messages, channel configuration, notifications, and error messages.
    • Added Azerbaijani pluralized message counts and formatted interface text.
    • Added Azerbaijani to the available language selection.
  • Documentation

    • Updated localization documentation to mark Azerbaijani translation as complete.

Register the az locale in the runtime and regenerate its catalog.

The supplied runtime selector in source/graphics/TFT/TFTView_320x240.cpp:3734-3835 has no Azerbaijani language case and never calls lv_i18n_set_locale("az"). Adding locale/az.yml alone cannot make Azerbaijani selectable on the device. Add the language-selection wiring and, if the firmware uses checked-in generated inputs, include the regenerated locale/lv_i18n.c and locale/lv_i18n.h files.

Add ə glyph coverage before enabling Azerbaijani.

The generated ui_font_montserrat_12, ui_font_montserrat_14, ui_font_montserrat_16, and ui_font_montserrat_20 fonts do not map U+0259 (ə), and their LVGL fallbacks are unset. These translations can render missing-glyph boxes. Add the glyph or configure a fallback font.

Thanks for the review. Both points are handled, and one part cannot be finished inside this repository.

Locale registration

az is now in lv_i18n_language_pack in locale/lv_i18n.c, so lv_i18n_set_locale("az") resolves. The catalog was produced with the compile step documented in locale/README.md, then matched to the style of the committed file; clang-format 20.1.0, the version pinned in .trunk/trunk.yaml, reports no changes.

The language dropdown is a separate matter. language2val and val2language in TFTView_320x240.cpp map the dropdown position onto meshtastic.Language, and that enum has no Azerbaijani value. It holds Glyph coverage

U+018F (Ə) and U+0259 (ə) fall outside every range in all four Montserrat fonts: the range before them ends at 383 and the next one starts at 880. That touches generated font data rather than the locale, so it is a separate PR: #393. It adds 2 glyphs per font and 458 bytes of glyph bitmap per generated directory.

Two unrelated things I noticed while reading the selector, left alone here: setLocale calls lv_i18n_set_locale("cn") while the catalog name is zh-CN, and hu and ro have catalogs but no selector case.

3720-3724: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

The locale pack registers az, but the device's supported language selector has no Azerbaijani value or mapping, so users cannot select the new translation from the language dropdown. Add the Azerbaijani selector value and its locale mappings alongside this registration.
