scripts: per-app SSO first-login scripts (gitea/redmine/discourse)

Each script: full OIDC webflow per app (gitea /user/oauth2/cloudron, redmine /oauth?oauth_provider=1 GET-form, discourse /auth/oidc with CSRF + confirm-page token), TOTP from vault seed, session verify. Ran fleet-wide 2026-09-09: accounts created for all 32 org identities; gitea tokens + redmine/discourse api keys minted via admin levers and stored per identity in the vault. https://projects.knownelement.com/issues/942
