Audit and connection log pages were timing out due to expensive COUNT(*)
queries over large tables. This commit adds opt-in count capping: requests can
return a `count_cap` field signaling that the count was truncated at a threshold,
avoiding full table scans that caused page timeouts.
Text-cast UUID comparisons in regosql-generated authorization queries
also contributed to the slowdown by preventing index usage for connection
and audit log queries. These now emit native UUID operators.
Frontend changes handle the capped state in usePaginatedQuery and
PaginationWidget, optionally displaying a capped count in the pagination
UI (e.g. "Showing 2,076 to 2,100 of 2,000+ logs")

This PR adds the backend implementation for modifying task prompts. Part
of https://github.com/coder/internal/issues/1084
## Changes
- New `UpdateTaskPrompt` database query to update task prompts
- New PATCH `/api/v2/tasks/{task}/prompt` endpoint
## Notes
This is part 1 of a 2-part PR stack. The frontend UI will be added in a
follow-up PR based on this branch

This is the third PR for moving connection events out of the audit log.
This PR populates `count` on `ConnectionLogResponse` using a separate query, to preemptively mitigate the issue described in #17689. It's structurally identical to a portion of https://github.com/coder/coder/pull/18600, but for the connection log instead of the audit log.
Future PRs:
- Implement a table in the Web UI for viewing connection logs.
- Write a query to delete old events from the audit log, call it from dbpurge.
- Write documentation for the endpoint / feature
Closes#17689
This PR optimizes the audit logs query performance by extracting the
count operation into a separate query and replacing the OR-based
workspace_builds with conditional joins.
## Query changes
* Extracted count query to separate one
* Replaced single `workspace_builds` join with OR conditions with
separate conditional joins
* Added conditional joins
* `wb_build` for workspace_build audit logs (which is a direct lookup)
* `wb_workspace` for workspace create audit logs (via workspace)
Optimized AuditLogsOffset query:

New CountAuditLogs query:

Joins in fields like `username`, `avatar_url`, `organization_name`,
`template_name` to `workspaces` via a **view**.
The view must be maintained moving forward, but this prevents needing to
add RBAC permissions to fetch related workspace fields.
* chore: Rewrite rbac rego -> SQL clause
Previous code was challenging to read with edge cases
- bug: OrgAdmin could not make new groups
- Also refactor some function names
