## Context
Initial work for Top for Postgres - adds a "Sessions" section under a
new Observability segment "Database Connections"
NOTE: All the copywriting and naming might change - not sure what's an
ideal title for this
We'll also be iteratively building on top of this UI, adding more
actionable signals instead of just information
Changes are featured flagged, off for public
- This would essentially replace the "View ongoing queries" in the SQL
Editor by providing a dedicated UI
- It checks against `pg_stat_activity` as per the ongoing queries UI
- We'll also subsequently deprecate the "Ongoing queries" UI in the SQL
editor
- Defaults into a "live mode" where the data is refreshed every 3
seconds via long-polling

- Supports filtering by state

- Users can also terminate queries through here

# Release Notes
* **New Features**
* Added an Observability **Database Connections** page with a live
**Sessions** activity table (state/roles filtering, blocked-by details,
session duration, and per-session termination with confirmation).
* Included a **Live/Pause** toggle to control automatic refresh (~3
seconds).
* **Enhancements**
* Improved Reports selection filtering: supports optional option
quantities, better popover styling, sorted apply behavior, and shows
quantity inline.
* Query performance duration formatting now supports configurable
decimal precision.
* Tooltips can now render richer content (string or React node).

Add a Query Performance page implementation powered by
[supamonitor](https://github.com/supabase/supamonitor).
[Context](https://linear.app/supabase/project/build-extension-for-supabase-query-insights-df4fb145352c/overview)
This looks largely the same as the pg_stat_monitor implementation:

Only available on projects on custom AMI - existing users are unaffected

## Summary by CodeRabbit
* **New Features**
* Supamonitor-based query performance view: charts, aggregated metrics,
date-range controls, and export/download.
* Added "Application" column for per-application tracking.
* Interactive Supamonitor grid: sorting, filtering, keyboard navigation,
selection, retry/error handling.
* Automatic per-project Supamonitor detection with toggleable UI
integration.
* **Bug Fixes**
* Chart latency calculation prefers histogram data for more accurate
p95.
* **Documentation**
* Minor blog formatting fix.

* feat: setup chart area and tabs
This sets up the area where we can expect the insights chart as well as the tabs mechanism.
* feat: parse pg_stat_monitor logs as json
* feat: create query perf chart utils and move transfrom function
Created a utils file for our QueryPerformanceChart component. This moves the logs to JSON transform function there.
* feat: add timerange to chart
* feat: add date selector to query perf overview
This adds the selector to the top right of the page allowing the user to switch between last hour, 3 hours and 24 hours
* feat: modify chart component to accomodate hiding bits
* feat: add metrics to each tab
* chore: update to 60 min by default and some css
* feat: centralise data parsing for logs
* feat: clean up filters bar
This rewires the export to give you the aggregate pg_stat_monitor data. Also removes unused buttons and filters.
* feat: percentiles for query latency chart
* feat: filter out non evenets from pg_stat_monitor logs
* feat: utils for cache misses and hits
* feat: add selected query to chart on click
* feat: add click through to query panel
* chore: tidy up files
* chore: distinction between selected and open panel
* feat: move query performance fully into reports area
* fix: preserve query params on reports link
* fix: remove right icon syntax in report menu
* chore: remove cache misses from cache chart
* refactor: backwards compatibility for statements if right db version isnt available
* chore: delete randomly generated empty file
* chore: tidy up unused imports and vars
* chore: remove console logs
* chore: remove isMounted from query perf
* fix: cmd k query perf path
* feat: simplify query latency only p50 and p95
This seems to give us a more accurate reading as we can calculate these two
* fix: cache hit rate not showing inside query details
* chore: chart bg colour adjust
So it contrasts a little better on light mode.
* feat: show selected query on other verticals
* feat: bring back symlink in advisors
* fix: human readable formatting for total consumed times
* chore: accidental turkish spelling of performance
* fix: imports for renamed utils file
* feat: add tests for formatDuration util
