Tidy up file handling, team roles and integrations (#358)

* Contain upload paths and gate the actions only a login guarded

Stored file URLs are resolved inside the upload root and refused when
they climb out; every stored URL is checked to be this workshop's own
upload; logo and background uploads are decoded and re-encoded so no
SVG or mislabelled file reaches the disk, and an old SVG is only ever
offered as a sandboxed download.

Deleting workshop content, exporting or restoring a backup, running the
legacy importers and changing the subscription now need an owner or
admin; backups are capped before they are read. The free-text customer
mail needs a permission and a customer's own address. An import is
checked against the file that was staged, not the kind the caller
named.

* Close the AI sandbox, the invitation escalation and the webhook trust gaps

The AI SQL guard now finds every table a query touches, including comma
lists, subqueries and CTEs, and the temporary views it creates are
discarded before the connection goes back to the pool; every raw query
in the app names its schema so none can land on a stale view. A chat
message can only be appended to the caller's own chat.

Inviting needs an owner or admin, only an owner may invite an admin,
invitation tokens never leave the server, and accepting an invitation no
longer marks the address verified: the sign-up sends the usual mail.

Inbound SMS webhooks verify the vendor's signature (Twilio always,
Telnyx and Vonage once the workshop pastes the key), PayPal and Vipps
payments are only recorded against the invoice the order was created
for, and a couple of secret compares are timing-safe.

* Send a pending invitation again

The copy-link button went with the token, so the team page gets a resend
button instead: a fresh link, seven more days, the old link retired, and
an audit entry. Owners and admins only.

* Drop an import the permission move left behind

* Keep the recipient check out of the server action module

+ * 3. Child tables (service_parts, payments, etc.) are scoped via JOIN to

+ * 4. The orgId is regex-validated (CUID characters only) and then string

 Note: camelCase columns MUST be double-quoted in SQL (e.g. "licensePlate", "totalAmount").
 Organization filtering is applied automatically — do NOT add WHERE "organizationId" = ... yourself.
+Join tables with explicit JOIN ... ON. Comma-separated tables in FROM (FROM a, b) are rejected, as are LATERAL, TABLESAMPLE and row locks. CTEs (WITH name AS (...)) are allowed.
 
 IMPORTANT: Linking to pages
 Always include id columns in your queries — for the primary entity AND any related entities (vehicle, customer, etc.). When displaying results, add markdown links for ALL entities present in the row. Use these URL patterns:
