## Context
Very tiny one - just supports clicking to copy PID from the Activity Row
in Database Connections
Will be useful for diving into details of the query with the Assistant
if needed

## Context
Building on top of "Database Connections" - this adds a top summary
section, again from `pg_stat_activity`

src="https://github.com/user-attachments/assets/f4968193-0a5f-4754-a630-40685b747999"
/>
Each block comes with a tooltip in hopes to educate the significance of
each metric
- Connections: Spread of connections per database role
<img width="313" height="164" alt="image"
src="https://github.com/user-attachments/assets/8ceeab5d-b960-4be3-9a5b-8600bd5cf303"
/>
- Active queries: Rough representative of activity
<img width="350" height="196" alt="image"
src="https://github.com/user-attachments/assets/f9705ff1-a869-409a-86b6-50170a169674"
/>
- Idle in transaction: Important to identify as this indicates locks
(Suggests root cause)
<img width="350" height="196" alt="image"
src="https://github.com/user-attachments/assets/f9705ff1-a869-409a-86b6-50170a169674"
/>
- Blocked queries: Also important to identify stuck queries
<img width="335" height="183" alt="image"
src="https://github.com/user-attachments/assets/57255fb8-24f6-4ddd-aa54-850a77173b5c"
/>
- Longest running query: Might be useful to identify unusually long
queries
- Will be `text-warning` if exceeds 30 seconds for active queries,
`text-destructive` if exceeds 10 seconds for queries idle in transaction
<img width="342" height="119" alt="image"
src="https://github.com/user-attachments/assets/f6783b43-058a-4a32-a40c-0bc64f23d2ce"
/>
"Summarize activity" CTA leverages on the Assistant to give a quick
overview - highlights any potential issues for quick reference

## Other changes
- Hides "View running queries" in SQL Editor if `topForPostgres` feature
flag is enabled (since this UI is meant to replace that)

## Summary by CodeRabbit

(connections, longest-running, active, blocked, idle-in-transaction) and
an interactive “Longest running” PID selector.

timestamped, activity-aware summary chat.
* **Improvements**
* Enhanced live activity refresh (including window-focus updates) and
standardized duration warning thresholds for active and
idle-in-transaction sessions.
* Improved hover details for query previews and allowed richer tooltip
content for metric labels.
* **Feature Changes**
* Gated the “View running queries” bottom panel behind a feature flag.
* **Bug Fixes**
* Refined running-too-long badge and warning styling for
idle-in-transaction cases.

## 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

src="https://github.com/user-attachments/assets/562f8fbe-2dc6-48e7-8ec0-de7ffb8348d1"
/>
- Users can also terminate queries through here
