chrisfu 5077e1335d feat(gitea): SPNEGO Kerberos SSO for git.prole.org
Three-part fix to make browser and curl SPNEGO auth work end-to-end:

1. spnego-proxy: issue WWW-Authenticate: Negotiate challenge when no
   Authorization header is present so Chrome (with AuthServerAllowlist)
   and curl --negotiate automatically present Kerberos tokens. Previously
   the proxy only validated tokens if the client proactively sent them.
   Pass-through preserved for non-Negotiate schemes (Basic/token) so
   git CLI users with PATs continue to work via Gitea own auth.

2. gitea_spnego_keytab.yml: new Ansible playbook that provisions the
   gitea-http AD account (AES-only, msDS-SupportedEncryptionTypes=24),
   registers SPN HTTP/git.prole.org, resets the password to derive fresh
   AES keys, exports the domain keytab, and rekeys it to principal name
   HTTP/git.prole.org@PROLE.ORG that gokrb5 needs for keytab lookup.
   Key lesson: samba-tool exportkeytab --principal=HTTP/... returns empty;
   must export full domain keytab and rekey in Python.

3. init_gitea.sh: add setup_gitea_spnego() calling the Ansible playbook
   in k3s mode as part of the standard deploy flow, with inline notes
   on every non-obvious constraint discovered during this work.
