docs: promote /web from develop for backup-restore, Log2RAM and Network Flow guides

Brings 69 files from develop under /web/:
- Full Backup & Restore section (11 pages EN + ES: overview, how-it-works, destinations,
  creating backups, scheduled jobs, restoring, cross-kernel hydration)
- Log2RAM dedicated block in post-install/optional with commands + upstream link
- Network Flow diagram documented on monitor/dashboard/network
- Rewritten category descriptions in post-install/customizable
- Fixed automated.json thresholds + link to Log2RAM section
- Updated screenshots (network-flow-overview, storage-top-row, vms modals)

No code, config or AppImage binaries touched — /web/ scope only. Merging deploys
the documentation site to the current beta release notes.
