feat(achievements): dedicated /achievements page with locked/unlocked list

Pre-v1.4.15 the page silently dropped locked achievements, so the user
only saw what they had already earned. Now every badge renders — locked
ones are grayed out with a "Locked" badge, criterion hint
({current} / {target}), and a progress bar. Unlocked entries keep the
existing primary-gradient card with the "Completed on …" footer.

Achievements are grouped by a new `category` axis (medication, vitals,
security, engagement) — derived in `getAchievementCategory()` so a
metric is always in exactly one bucket. Inside a category, unlocked
items sort first; among locked items the closest-to-unlock one ranks
first so the user always sees their immediate next goal at the top.

The sidebar link to /achievements was already in place under the
user-area group; this commit only adds the new locked/grouped render
plus an e2e smoke spec that walks the desktop sidebar → click →
heading visible path.

i18n: 9 new keys under `achievements.*` (locked, criterionHint,
progressPercent, categories.{medication,vitals,security,engagement},
dashboardCard.{title,viewAll,empty}) — EN + DE. C4's parity audit will
sweep later.

Tests: +9 unit (groupByCategory ordering + page render in EN/DE) +
1 e2e (sidebar → /achievements). 909 / 909 unit pass.
