Declare the LDAP and SSO auth plugins as proper meta/addons entries
(mechanism/source/version, github-releases update monitoring, url/tag/
md5/guid under config:) and resolve the install parameters in vars from
the addon config instead of hardcoding them.
Move biber's login journeys into the mandated per-addon Playwright specs:
ldap-authentication tests the LDAP manual login, sso-authentication the
OIDC round-trip. Because a Jellyfin user binds to exactly one auth
provider, the LDAP spec skips while SSO is active — the ldap-only matrix
variant owns that path — so a single test user suffices and the specs
stay parallel-safe. playwright.spec.js keeps guest + native admin;
biber's generic persona is opted out via PERSONA_BIBER_BLOCKED.
Also fill the optional meta/info.yml fields (homepage, video, display).
