Add local Supabase backend foundation: schema, RLS, and RLS tests
- supabase/config.toml: local dev stack config, pinned to the app's fixed dev server port, email confirmation required (hard verification gate per organized-ideas.md). - Initial schema migration: profiles/roles, the public/private catalog tables (manufacturers, device categories, port types, cable types, device templates + ports) with the shared is_public/owner_id RLS pattern, a generalized catalog_submissions review-queue table, and diagrams as JSONB documents (+ collaborators, snapshots) rather than fully normalized -- see the migration's header comment for why. - pgTAP RLS test suite (23 assertions) covering catalog visibility and promotion-in-place, diagram owner/collaborator/admin/super-admin visibility and edit permissions, submission visibility, and role escalation. Caught and fixed a real infinite-recursion bug between the diagrams and diagram_collaborators policies before this ever touched real data. - vite.config.ts: pinned dev server port so Supabase Auth's redirect allow-list doesn't silently break if Vite floats to another port.

-- RLS policy tests (pgTAP), per organized-ideas.md §1: "automated tests
|
||||
-- specifically for the RLS policies... the actual security boundary once
|
||||
-- roles matter." Run with: supabase test db
|
||||
--
|
||||
-- device_categories is used as the representative test for the shared
|
||||
-- catalog pattern (manufacturers/port_types/cable_types/device_templates
|
||||
-- all use the identical is_public/owner_id policy shape) rather than
|
||||
-- repeating the same assertions five times.
|
||||
--
|
||||
-- Approach: fixture users/rows are set up as the postgres superuser (which
|
||||
-- bypasses RLS entirely), then we switch to the `authenticated` role and
|
||||
-- impersonate each fixture user in turn by setting the JWT `sub` claim that
|
||||
-- auth.uid() reads — the same mechanism Supabase's own runtime uses.
|
||||
--
|
||||
-- Note on UPDATE/DELETE vs. INSERT RLS failures: an INSERT whose new row
|
||||
-- fails WITH CHECK always raises 42501. An UPDATE/DELETE whose target row
|
||||
-- doesn't satisfy USING is simply excluded from the statement — 0 rows
|
||||
-- affected, no error. Only an UPDATE where USING passes (the row is yours
|
||||
-- to touch) but the *new* values fail WITH CHECK actually throws. Tests
|
||||
-- below use throws_ok only for genuine WITH CHECK failures, and a plain
|
||||
-- update-then-assert-unchanged for the "you can't even touch this row"
|
||||
-- case.
