fix(web): translate series, calendar and push all strings, fix search interval hint

[vavallee]

Summary

Fixes UI text bugs found while translating Norwegian and Swedish in #2994.

1. Wrong advice in the search interval hint. search.interval is the gap between scheduled sweeps (internal/scheduler/scheduler.go registers search-wanted as @every <interval>, clamped to 1h to 168h, read once at startup). The hint told rate limited users to reduce it, which makes Bindery search more often. It now says to choose a longer interval.
2. Hardcoded English in the Series page, the Calendar and Calibre's Push all to Calibre now goes through i18n.
3. Ellipses normalised to … across en.json prose, and in the other locales where it is mechanical.

Implementation notes

Area	Change
searchIntervalHint	Reworded in en.json. de, es, fr, nl, tl and id held the old wrong advice as untranslated English, so the key is removed there and falls back to the corrected English. ko never had the key.
CalendarPage	The month label no longer wraps on phones (whitespace-nowrap, min width). Hardcoded month and weekday arrays replaced with Intl.DateTimeFormat in i18n.resolvedLanguage, built and formatted in UTC so no offset can shift a label. Covers the month header, the releasingIn interpolation, the agenda day labels (Mar 5 / 5 mars), both weekday header rows and the document title.
SeriesPage	Heading, count (pluralised), Add Series, Rename, Add Book, Delete, empty states, missing and book count badges (pluralised), the shortlist switch, genre button, prompt, tooltips and results, Fill gaps and its results, the Hardcover panel (link button, heading, diff summary, format select, add / add all, loading, more missing), the status pill (now uses the existing bookStatus.* labels) and the document title. New keys are under series.*.
SeriesNameModal (sibling)	Name label, placeholder, validation and error messages, Cancel, Saving. The Add Series button and modal title in AuthorsPage now use the same key.
CalibreTab	The Push all to Calibre block (label, description, bridge warning, button, tooltip, queueing) and the whole CalibreSyncModal. New keys are under settings.calibre.pushAll.*.
Ellipses	en.json: 23 values ... to …, plus the matching inline t() defaults so inlineDefaults.test.ts stays green. de, es, fr, nl, tl, id and ko: translated values only. Values that were still verbatim English filler (common.deleting in de, es, fr, nl, tl and id, and discover.refreshing in de, fr and nl) are removed so they fall back to en.json. nb.json and sv.json were not touched (#2994).

English rendering is unchanged except: ellipses, Genres set on N books (was book(s)), N more missing book singular, and series status pills now read Imported / Wanted (capitalised, as on other pages) instead of the raw enum.

Follow-ups (not in this PR)

• The rest of CalibreTab.tsx is still hardcoded English: library path, write integration options, binary path, plugin URL, API key, path remap, Test connection, Library import, CWA section and import progress.
• AddSeriesBookModal.tsx and HardcoverSeriesLinkModal.tsx (opened from the Series page) are hardcoded English.
• The search interval <option> labels in GeneralTab.tsx (6 hours, 12 hours (default) and so on).
• ABSTab.tsx has hardcoded Searching..., Author, Book.
• Most pages set document.title from an English literal (Wanted, Search, History, Settings, Books, Users).
• The non-English locales still carry other English filler without ellipses, for example searchIntervalLabel and searchIntervalRestart. These should be removed so they fall back properly.

Checklist

• Tests added or updated
• Doc-update gate cleared (no docs describe these strings)
• Wiki pages updated if user-facing behaviour changed (not applicable)

Test plan

• cd web && npm ci && npm run lint (0 errors; the 7 warnings are already on main)
• npm run typecheck
• npx vitest run: 1226 of 1227 passed. The one failure was a 5s timeout in HistoryPage.test.tsx (a file this PR does not touch), and it passes when run on its own.
• npm run build
• After merging main (test(web): cover the least covered settings tabs, pages and API modules #3032): CalibreTab.coverage.test.tsx now matches on i18n keys. The full suite passed 1547 of 1548; the one failure was a library import timing test in that file, in a section this PR does not change, and the file passed 3 of 3 runs on its own.
• New tests: CalendarPage.test.tsx (English and French month, weekday and day labels), SeriesPage.test.tsx "renders its labels from the active locale", CalibreSyncModal.test.tsx translation cases. I ran the locale tests against the original components and all three failed, so they do catch the old hardcoded strings.

Reviewed the full diff. Overall clean i18n sweep with good test coverage for locale-switching cases.

One item to verify before merge

SeriesPage.tsx (the Hardcover format select, around the fillMediaType block) now calls t('common.ebook'), t('common.audiobook'), and t('common.both') with no inline defaults, and the diff does not add these three keys to en.json. If they do not pre-exist in en.json the format select renders the raw key string (common.ebook etc.) in every language. The new SeriesPage.test.tsx locale test does not exercise the diff panel (it needs a hardcoverLink with missingCount > 0), so the gap would not be caught by CI. Worth a quick check: jq '.common | keys' web/src/i18n/locales/en.json

Everything else looks good

• The search-interval hint fix is correct: the scheduler registers the job as @every interval (clamped 1h-168h), so a shorter interval searches more often. Old advice was backwards; new wording is right.
• CalendarPage uses timeZone UTC throughout and anchors weekday names to 2023-01-01 (a Sunday, matching getDay()==0). UTC construction prevents local-offset edge cases. Switching key={d} to key={i} on weekday headers is correct since narrow names can collide (two S, two T).
• Removing searchIntervalHint and other stale English filler from de/es/fr/nl/tl/id correctly falls back to the fixed en.json rather than showing old wrong advice.
• Pluralisation of series.genre.applied (_one/_other) replaces the hacky book(s) suffix.
• The three new test suites (CalendarPage, SeriesPage translations, CalibreSyncModal translations) each assert on the pre-fix behaviour failing, so they actually catch the regression they describe.
