feat: new workflow library

[maryhipp]

Summary

Add new workflow library UI:

• Library is now in a large modal with cards instead of slim list (potential for list view as a future enhancement).
• Workflows divvied up into last 5 opened (Recent), user workflows (Your Workflows), and default workflows (Browse Workflows).
• Default workflows are categorized by predefined categories and tags. The categories and tags are tentative.

Internal changes

• Add a generated tags column to workflow library table, which pulls the tags out of the workflow JSON.
• Add tag searching to workflow records service & endpoint.
• Add a counts method to workflow records service & endpoint, which can be used to get the number of workflows in the any of the provided categories and with any of the provided tags. This is used to prevent perf issues with loading and deserializing literally all workflows just to count them.
• Previously, the workflow records service bumped the opened at timestamp when the get method was called. That does not really work - we call get all the time. It doesn't map to the user opening the workflow. There is a new method and endpoint to set the timestamp to the current time. The frontend hits this endpoint when the user loads a workflow to view or edit.
• Bumped RTK to latest to get infinite query support, used in the new library.

TODO:

• Iterate on styling and layout.
• Fix/add RTK query cache invalidation for all workflow library endpoints. For example, if you sort workflows by opened at, then open a workflow, the library does not re-sort itself. We need to invalidate the query cache for the library so it re-fetches the list with the updated timestamps.
• Internal code cleanup, especially the react components.
