One vocabulary: Knowledge, tools, and connectors in plain words

- Sources (the collection) are called Knowledge: the settings page (now
  /settings/knowledge; /settings/sources redirects), the composer and
  agent pickers, Add knowledge, and "syncs into Knowledge" on connectors.
  Citations keep "sources". All seven locales.
- Connector cards describe what they do ("Syncs into Knowledge", "Looks
  things up", "Takes actions") and drop publisher labels ("Built in",
  "Preset"). Filters read "Files & storage" and "Docs & wikis" so
  "knowledge" means one thing.
- Custom tools are tools: "Add custom tool". The agent picker no longer
  splits built-in tools into "Built-in" and "Default".
- Confluence is one card: syncing pages into Knowledge and the Jira &
  Confluence MCP actions (part_of on the preset) share a page. The part
  shows on its own when Confluence sync is not set up.
