Merge pull request 'Merge development into main (v4.1.0 release)' (#169) from development into main

Fixes #160: update_wiki_page was renaming pages to "unnamed"

Root causes:
1. page_name wasn't URL-encoded, breaking pages with special chars like ':'
2. PATCH request was missing 'title' field, causing Gitea to use default name

Changes:
- Add URL encoding (urllib.parse.quote) to get_wiki_page, update_wiki_page, delete_wiki_page
- Add 'title': page_name to update_wiki_page payload to preserve page name
