328 more routes used a JSON body as a dict straight from
request.get_json(), so a body of null, [] or a bare string crashed them
into a 500. Bare reads become json_object(); the
'get_json(silent=True) or {}' reads of action routes become
json_object(optional=True), which still treats a missing body as {}.
Routes that take arrays or pass the body through untouched are left
alone. The full backend suite shows no new failures.
Also carries three files' bare section citations (apps, backups,
notifications) and the extended citation guard, which needed them.
Introduce team invitation support and a revamped email subsystem plus admin features. Adds Invitation model and API endpoints (create, list, revoke, resend, validate) and integrates invitation validation into user registration.

Refactors email API to manage domains, accounts, aliases, forwarding, DNS providers, spamassassin, Roundcube/Postfix services and queue/log endpoints. Adds several backend services (invitation, DNS provider, DKIM, Dovecot, Postfix, Roundcube, SpamAssassin, permission service) and a DB migration for permissions/invitations. Enhances admin API with permission management and activity dashboard endpoints, extends audit log actions, and adds a permission_required RBAC decorator. Includes frontend additions for settings/invitations UI and miscellaneous config/service updates and tests.
