PER-15119: remove deprecated pdp-api.permit.io host from docs (#638)

* PER-15119: remove deprecated pdp-api.permit.io host from docs

The shared public PDP at pdp-api.permit.io is a legacy/decommissioned
instance and is no longer in use. Remove all references to that host:

- PDP API Reference page: drop the dead online redoc iframe embed and
  keep the local-PDP OpenAPI/redoc guidance.
- SDK redoc deep-links (all-tenants, url-mapping): repoint to the
  internal /api/pdp-api-reference page.
- authz-query curl examples (all-tenants, authorized_users,
  user-permissions): repoint to the local PDP at http://localhost:7766,
  matching the convention used elsewhere in the docs.

* PER-15119: fix local PDP redoc/openapi URL to localhost:7766

The PDP API Reference page referenced localhost:7000, which is the
container-internal port. The host-mapped port used everywhere else in
the docs (via -p 7766:7000) is 7766. Repoint the browser-facing
openapi.json/redoc URLs to localhost:7766 for consistency.
