feat(pages): Add subdomain routing and default config support

- Update subdomain parser to use {repo}-{owner}.{domain} format
- Add middleware to intercept Pages subdomain requests
- Generate default config when Pages enabled but no .gitea/landing.yaml
- Pages are public landing pages (accessible even for private repos)
