docs(cloud): add Maintenance Windows page for Enterprise

[dragnot]

Summary

Add a new Maintenance Windows page under Cloud DBaaS describing how maintenance works for FalkorDB Cloud, with scheduling flexibility as an Enterprise only feature.

Changes

• New page cloud/maintenance-windows.md (nav_order 6, after Features):
  • Availability by tier: Enterprise gets a predefined window set with the account team. Pro and below are upgraded by FalkorDB with advance notice.
  • Scheduling: window up to 4 hours, available slots Sunday to Wednesday 6 AM to 8 PM UTC, with a footnote that the window can be discussed and extended for Enterprise customers.
  • Expected impact: Standalone has a short downtime on restart. Replication/Cluster has no downtime, only a brief latency spike.
  • Urgent maintenance and Getting Support sections.
  • FAQ accordion matching the existing tier pages.

Testing

Docs-only change. Page follows the existing Cloud DBaaS page conventions (front matter, FAQ accordion include, support links). Verified front matter and include syntax against existing tier pages.

Memory / Performance Impact

N/A (docs-only).

@dudizimber This is the MW update we discussed. Please approve @alexberesnev, let me know if the wording does not conflict with any commercial commitment we have -- please approve both or tell me what to change

@gkorland FYI -- I hope you can aim to have MW not restricted to specific hours - or I can remove the hours and leave Sun-Wed
