refactor(astrolabe): reframe UI as semantic search service

Update all user-facing text to focus on Astroglobe as a semantic
search service for Nextcloud users:

- info.xml: New description focusing on finding content by meaning
- Settings sections: Renamed from "MCP Server" to "Astroglobe"
- Personal settings: Reframed as content indexing controls
- Admin settings: Reframed as semantic search administration
- OAuth flow: Explains semantic search benefits to users

Key messaging changes:
- "MCP Server" → "Astroglobe"
- "Grant Background Access" → "Enable Semantic Search"
- "Vector Sync" → "Content Indexing"
- Focus on user benefits: natural language search, finding by meaning
