* chore: remove InsertWorkspaceAgentStat query
InsertWorkspaceAgentStats (batch) exists. We only used the singular in
a single unit test place. Removing the single for the batch, reducing
the interface size.
* fix: don't make session counts cumulative
This made for some weird tracking... we want the point-in-time
number of counts!
* Add databasefake query for getting agent stats
* Add deployment stats endpoint
* The query... works?!?
* Fix aggregation query
* Select from multiple tables instead
* Fix continuous stats
* Increase period of stat refreshes
* Add workspace counts to deployment stats
* fmt
* Add a slight bit of responsiveness
* Fix template version editor overflow
* Add refresh button
* Fix font family on button
* Fix latest stat being reported
* Revert agent conn stats
* Fix linting error
* Fix tests
* Fix gen
* Fix migrations
* Block on sending stat updates
* Add test fixtures
* Fix response structure
* make gen
* chore: convert workspace agent stats from json to table
* chore: convert agent stats to use a table
Backwards compatibility becomes hard when all agent stats are in a JSON blob.
We also want to query this table for new agents that are failing health checks
so we can display it in the UI.
* Fix migration using default values
