fix(projects): perm-gate create + apikey-via-Bearer + introspect with apikey

Three coupled fixes so non-admin agents (e.g. nav, role=mgr) can
actually create projects through hf-cli with their API key:

1. POST /projects no longer hardcodes is_admin. It checks the global
   `project.create` perm via role_permissions (admin still wins via
   is_admin short-circuit). Permission-denied 403 message names the
   exact perm.

2. /auth/me/permissions now uses get_current_user_or_apikey (was
   get_current_user JWT-only). This is what hf-cli hits to populate
   its local permission cache that drives the "not permitted" gate;
   previously every API-key-authed agent saw all commands as gated.

3. get_current_user_or_apikey now also accepts an API key delivered
   via Authorization: Bearer (in addition to X-API-Key). hf-cli only
   knows Bearer; trying to JWT-decode an API key string would fail —
   so on decode failure, fall through to the API key lookup. Keeps
   X-API-Key behavior unchanged.

4. init_bootstrap: add `project.create` to DEFAULT_PERMISSIONS and to
   _MGR_PERMISSIONS so admin (auto-all) + mgr both get it on seed.

Bug came to light when manager-agent reported `hf project list`/`create`
returned `not permitted`. Root cause: hf-cli calls /auth/me/permissions
with the API key via Bearer header → 401 → state.Known=false → every
command in the surface is gated false locally. Even after the local
gate, POST /projects would still 403 due to the hardcoded admin check.
All four steps above are required end-to-end.
