Website: Add support for new usage statistics (#40879)

Closes: https://github.com/fleetdm/fleet/issues/39836

Changes:
- Added `fleetMaintainedAppsWindows` and `fleetMaintainedAppsMacOS`
attributes to the HistoricalUsageSnapshot model
- Added `fleetMaintainedAppsWindows` and `fleetMaintainedAppsMacOS` as
inputs to the receive-usage-analytics webhook


Note: This pull request requires database migrations and should only be
merged after the website's database is updated while it is in
maintenance mode.
