Invitation flow with per-user quota (#332)
Any authenticated user can invite an e-mail address; the mailed
single-use token lets exactly one signup through even while
registration is closed. Open (pending, unexpired) invitations count
against the new instance setting invitations.maxOpenPerUser (default 5,
0 disables inviting) — plus a 20/day per-user rate limit so a
revoke-and-recreate loop cannot become a mail cannon. Only the SHA-256
token hash is stored (auth-tokens pattern); a failed signup (taken
username) un-redeems the token so the invitee can retry.

Surfaces: invitations section in the user settings (list, invite,
revoke, quota line; wide table in a focusable .table-scroll region),
signup page reads ?invitation=<token> (preview banner, e-mail prefill,
closed-mode gate opens only for a previewed-valid token), admin general
card gets the quota field (flat RHF name per #322; VS-NfD marked and
hideable).

Governance: audit actions invitation.created/revoked/accepted
(catalogue 1.10), VS-NfD profile entry (compliant: 0) + hardening-guide
row, i18n de+en including the invitation mail template.

Tests: api e2e-db (mail link, closed-mode single-use signup with
un-redeem on failure, quota + revoke frees slot, quota 0 = 403, auth
matrix), new web e2e pack invitations.spec.ts (full UI loop through
Mailpit, wired into ci.yml with its own rate-limit reset), a11y scan
waits for the new section. Full api suite (107 files / 607 tests),
auth/admin-settings/a11y packs green against a fresh local stack.

Closes #332
