docs: fix broken descriptions (cube-js#10617)

* docs: fix broken markdown links in frontmatter descriptions

Mintlify renders description as plain text subtitle, so markdown
reference links [text][ref] displayed as raw syntax. Replaced with
plain text across 41 pages.

Made-with: Cursor

* docs: reorganize folder structure and update navigation

- Rename docs/caching to docs/pre-aggregations
- Rename admin/deployment/monitoring to admin/monitoring/monitoring-integrations
- Move account & billing pages into admin/account-billing folder
- Move support page from deployment to account-billing
- Add sidebarTitle to monitoring integration pages
- Use root property for all API groups in docs.json
- Update all cross-references across 100+ files

Made-with: Cursor
