feat(MAT-57): Add Confluence write & create tools to voice and text chat

- Add create_confluence_page tool to voice mode (basic auth)
- Add confluence_update_page and confluence_create_page tools to text chat (OAuth)
- Fix update tool: wrap each paragraph in <p> tags instead of single wrapper
- Update system prompt to mention create capability

Previously only search/read were available. User reported bot couldn't
write to or create Confluence pages — because the tools didn't exist.
