Part of #145.
Twenty-three files across the task list zone: the list and card views,
sorting and grouping, multi-select and its toolbar and help sheet,
archived tasks, the assignee card, the chore action menu, the
nudge/NFC/photo modals, the rich text editor, the scan panel, the
notification templates and the keyboard-shortcut toasts.
Extends the existing `chores` namespace, so `src/i18n/config.js` is
untouched.
English only — no translations, no behaviour change. Every t() value is
checked against this branch's base: the string must appear
character-for-character in the code it replaces (247 call sites).
Two values are matched loosely and worth naming: archived.closeMultiSelect
in both the archived view and the toolbar. The base builds that tooltip as
`${size === 0 ? 'Close' : 'Clear'} multi-select (Esc)`, so only one branch
of the ternary exists contiguously in the source. Both keys hold exactly
what each branch renders; the tooltip is kept whole so a translator can
reorder it.
Rebased on current `develop` again after #215 and #216 landed — the
dictionary conflict was theirs, not the code's. No code file in this PR
was touched upstream in the meantime.
