fix(dashboard): disambiguate quick-add submenu labels (no more double "Hinzufügen")

The dashboard "Add" dropdown rendered two menu items whose visible text
both resolved to bare nouns ("Messung" / "Stimmungseintrag" in DE,
"Measurement" / "Mood entry" in EN). Combined with the trigger label
("Hinzufügen" / "Add"), screen-reader users effectively heard the same
verb three times in a row with no signal which row did what.

Update both translations to self-contained verb-phrases:
- DE: "Messung erfassen" / "Stimmung erfassen"
- EN: "Log measurement" / "Log mood"

Add `src/app/__tests__/quick-add-labels.test.ts` to lock the contract:
both labels must be non-empty, distinct from each other, and distinct
from `common.add` (the trigger). The test loads `messages/{en,de}.json`
directly so any future translator who collapses the labels back to
"Hinzufügen" or "Add" gets a red bar before merge.

+/**
+ * v1.4.15 phase-A3 fix #1 — the dashboard "Hinzufügen" / "Add" dropdown used
+ * to render two menu items whose visible labels both resolved to the bare
+ * verb ("Hinzufügen" in DE, "Add" in EN). The dropdown trigger ALSO says
+ * "Hinzufügen", so a screen-reader user heard "Hinzufügen, Hinzufügen,
+ * Hinzufügen" with no way to tell the entries apart.
+ *
+ * The fix is to give each entry a self-contained noun-phrase label
+ * ("Messung erfassen", "Stimmung erfassen") that doesn't collide with the
+ * trigger or the other entry. This guard locks that contract in: if anyone
+ * later edits one of the two values to match the other (or to match
+ * `common.add`), the test fails before the regression ships.
+ *
+ * Lives under `src/app/__tests__` because the consumer is the dashboard
+ * page (`src/app/page.tsx`); the keys themselves are namespaced under
+ * `dashboard.*` in both messages files.
