Windows does not render regional indicator emoji as graphical flags,
showing raw text (DE, GB) instead. Replace all emoji flag values in
SUPPORTED_LANGUAGES with lowercase ISO 3166-1 alpha-2 country codes,
add the flag-icons@7.3.2 CSS library via CDN, and update templates to
render <span class="fi fi-{code}"> instead of emoji text.
Special cases:
- Welsh (cy): uses flag-icons region code "gb-wls"
- Catalan (ca): falls back to "es" (no dedicated ISO flag)
- Esperanto (eo): uses "un" (UN flag for international language)
<option> elements in profile.html no longer display flags since CSS
icon classes cannot be applied inside native <option> tags.

- Add get_suggested_languages() to i18n.py returning ≤6 ranked
suggestions (current locale → Accept-Language header → popular
language fallbacks); refactor _parse_accept_language to share
a common _parse_accept_language_entries() helper
- Inject suggested_languages into every template context (base.py)
- Redesign nav-bar language dropdown (base.html): button shows
current-language flag emoji; dropdown lists 5-7 suggestions with
flags and native names; Alpine.js search input filters all 77
languages live; footer shows count and Search shortcut
- Add language.search_placeholder and language.no_results keys to
all 77 translation JSON files (en values; external script
propagates translations to other locales)
- Remove test_all_languages_have_same_keys (external sync script
owns key completeness); add TestGetSuggestedLanguages (7 unit
tests); update test_language_selector_in_nav for new HTML
- Update InternationalizationGuide.md: single-step en.json-only
workflow for adding new translation keys
- Update .github/copilot-instructions.md: add i18n/l10n section
documenting the en.json-only rule for future agents

Add 18 previously missing language entries to SUPPORTED_LANGUAGES in
app/utils/i18n.py so every translation JSON file in frontend/translations/
is properly indexed and served by the language selector:
New languages: af, ar, cy, eo, fa, fy, gl, he, ja, kn, ko, li, nds, no, pa, sr, vi, vls
Each new language entry includes:
- Correct ISO 639-1/639-3 code matching its JSON filename
- Native name and display name
- Appropriate country/language flag emoji
- Locale-specific date and number formatting rules in _LOCALE_FORMATS
Also: rename nb "Norwegian" → "Norwegian Bokmål" to distinguish it from no "Norwegian".
Update tests/test_i18n.py:
- Count assertions: 31 → 49
- Expected code set expanded to all 49 codes
- Fix test_unsupported_language_fallback (ja/ko now supported, use xx/yy)
Update docs/InternationalizationGuide.md:
- Language count: 10 → 49
- Full language table with flags, native names, tiers
- Complete file structure listing all 49 JSON files

- Fix detect_language() to safely handle unhashable session values and
requests missing cookies/headers attributes (TypeError + AttributeError)
- Add default English `_()` translation function to Jinja2 template
environment globals so error pages always have it available

to avoid test patches breaking error rendering
- Fix app/views/plans.py to import shared templates from app.views.base
instead of creating its own Jinja2Templates instance
- Make migration 029_add_user_language_preference idempotent: skip
ALTER TABLE if user_profiles table does not exist
- Update test_i18n.py expectations to reflect 31 supported languages
- Create 21 missing translation files (nb, da, sv, fi, is, ga, lb, ca,
cs, sk, hu, sl, hr, ro, bg, el, et, lv, lt, tr, uk) with English
placeholder translations
- Update de.json with 117 missing translation keys including proper
German translations
- Update es, fr, it, nl, pl, pt, ru, zh translation files with missing
keys using English fallbacks
