feat(dashboard): mobile layout, glass UI, context bottom nav + OIDC PKCE (#1079)

* feat(dashboard): mobile layout, glass tiles, plain-text countdown, place photos

- Rework the mobile dashboard: cover hero, separate boarding-pass card,
  trimmed atlas (trips + days only), stacked widgets
- New floating bottom tab bar with a centred context-aware + button
  (new trip / place / journey / entry depending on the page)
- Move profile + notifications into a small top strip on the dashboard
- Desktop: glassmorphic tiles (light + dark), neutral dark palette,
  plain-text countdown module, real place photos in the boarding pass

* i18n(dashboard): translate new dashboard keys across all locales

Fill the dashboard-rework keys (hero, atlas, fx, tz, upcoming, copy
dialog, aria labels, countdown) that were left as English placeholders,
plus the new startsIn/aria keys, for all 19 languages.

* feat(oidc): send PKCE (S256) in the OIDC login flow

The OIDC client now generates a code_verifier per login, sends the
S256 code_challenge on the authorize request and the code_verifier on
the token exchange. Works whether the provider has PKCE optional or
required (fixes login against providers that require PKCE, e.g. Pocket ID).
