fix(admin): source scoping + redirect URIs in admin OAuth registration

Takeover of #1558 (rebased onto master, admin/dist + admin-embedded regenerated so asset hashes match; source changes salvaged intact): - /admin/api/register-client now accepts source_id + federated_read (snake and camel case), validated fail-closed against the registered source list via the new normalizeAdminClientSourceScope (src/core/admin-source-scope.ts) before reaching registerClientManual — unknown or malformed ids are a 400, never a silently-hardcoded 'default'. Fixes #1490. - New requireAdmin-gated GET /admin/api/sources feeds the Register Agent form; the form now has a Write Source select + Read Sources checkboxes, and the agents table/drawer show each client's scope. - #1036: the Register Agent form now has a Redirect URIs textarea (one per line). When present, the POST carries redirectUris plus the authorization_code + refresh_token grants, mirroring the CLI's --redirect-uri grant-inference convention (src/commands/auth.ts). Backend plumbing already existed; this was UI-only. Tests: test/admin-source-scope.test.ts (normalization matrix), test/oauth.test.ts (registerClientManual persists source scope into AuthInfo), test/fix-wave-structural.test.ts (endpoint + form pins for #1490 and #1036).
