Adds `form_definition.locale` (default 'de'). When set to 'en', every
hardcoded German participant string flips to English: closed banner,
name field label + placeholder, summary card title/subtitle/term, all
banner copy, submit + chat send buttons (both default and in-flight),
chat empty state, chat placeholder, results section heading, validation
error prefixes ("Bitte beantworte" / "Please answer"), rate-limit
errors, and the boolean Yes/No labels in the per-type input component.
Shape:
- `lib/i18n.ts` exports `tr(locale, de, en)` — a tiny inline-strings
helper, no central catalog. New strings = inline both at call site.
- Components read the active locale via Svelte context
(`setLocale`/`useLocale`) so per-question-type inputs don't need a
new prop on `ParticipantInputProps`.
- `submit_label` override still wins over the localized default — so
forms that already set submit_label keep their custom text.
In-scope for this commit: participant page (`/f/<slug>`) only. Admin,
FormBuilder, FormBuilder type picker, builder-side strings ("Inhalt
(Markdown)", etc.) all still German. Per m/fdbck#3 the participant
surface was the most-visible audience; admin can follow in a separate
shift.
Motivation: upc-session-2026-5 is an English-audience form; chat is
enabled per m's intent so suppressing strings per-instance wasn't an
option. Per-instance locale was the right shape.

Anti-abuse layers
- 32-char base62 slugs (~190 bits entropy)
- in-memory rate-limit (30 posts / 5 min, 10 submits / 5 min, per IP+slug)
- honeypot field on forms + chat (silently dropped)
