Phase 1 of German support, and it fixes the Sunday-start date picker for PDF study deadlines.

The calendar fix

The weekday picker (showDatePicker in the PDF deadline sheet) started the week on Sunday only because the app hard-pinned supportedLocales: [Locale('en')] — generic English starts on Sunday, while the app's own heatmap/week views are already Monday-first. Now the app follows the device locale (en, de), so a German/EU device resolves to de and Material's date picker starts on Monday.

Foundation

Stands up the gen_l10n pipeline that didn't exist yet:

flutter: generate: true, l10n.yaml
lib/l10n/app_en.arb (template) + app_de.arb + generated AppLocalizations
main.dart: AppLocalizations.delegate + AppLocalizations.supportedLocales, locale follows the device; untranslated keys fall back to English

Pilot

The PDF deadline sheet (the picker's own screen, ~17 strings) is translated end-to-end as the established pattern for the rest of the app. Its widget test now installs the localization delegates; the English assertions are unchanged.

Scope

This is the foundation + one feature. The full app is ~980 strings across 532 files / 33 feature areas — those land in follow-up PRs, area by area. flutter analyze clean on the touched files; the deadline-sheet widget tests pass.

Note: needed a flutter pub get to repoint .dart_tool/package_config.json from a root-owned /root/.pub-cache (a prior sudo'd pub get) to your user cache — unrelated to this change but it was blocking gen-l10n's format step locally.
