Previously the connect button in post-payment messages and in 'My subscription' section opened the mini app (personal cabinet) when SUBSCRIPTION_MINI_APP_URL was set, ignoring the actual subscription URL. Now the real subscription URL is preferred, with the mini app used only as a fallback.
The bot's locales/*.json files do not contain the webapp-specific keys
(connect, extend_subscription, loading, etc.), so applyI18n was
overwriting the localized HTML defaults with raw key names.
Merge the bundled FALLBACK_I18N table with whatever the server provides
per language, letting server values override but falling back to the
in-bundle translations for keys the bot does not ship.
The Telegram Login Widget embeds oauth.telegram.org in an iframe; without
an explicit frame-src directive it fell back to default-src 'self' and was
blocked. Add frame-src https://oauth.telegram.org so the login flow loads.
Add a per-request nonce to inline <script type="application/json"> blocks
(webapp-config, i18n) so they survive script-src 'self' and locales/config
actually load in the browser. Also add 'unsafe-eval' to script-src so the
vendored telegram-widget.js (which uses eval/new Function) can initialise.
Unify error logging across services: replace logger.error(f"...{e}")
and logger.error(..., exc_info=True) with logger.exception() so the
stack trace is consistently captured.
