feat(frontend): new strip components, suggestions dropdown, empty state

CorrespondenzPersonBar (Row 1), CorrespondenzFilterControls (Row 2 with
live count + sort), CorrespondentSuggestionsDropdown (fetch-on-focus,
keyboard nav), SinglePersonHintBar, CorrespondenzEmptyState (recent
persons from localStorage). New i18n shim in messages-extra.ts until
root-owned paraglide files can be regenerated.

/**
* Extra message functions for i18n keys added after the last paraglide compile.
*
* TODO: Remove this file once the root-owned paraglide files in src/lib/paraglide/
* are regenerated (run `npm run dev` or the paraglide compile step as the owning user).
* At that point, these functions will be generated into _index.js and the components
* that import from here should switch back to importing from $lib/paraglide/messages.js.
*
* Note: these fall back to German only — locale switching is handled by the generated
* paraglide files, not this shim.
