## Problem
The Multigres log type is available in the legacy logs collections but
was missing from the new unified logs, so Multigres logs could not be
selected or viewed there.
## Fix
Wire the `multigres_logs` source into unified logs the same way the
other single-source types (Realtime, Supavisor, PgBouncer) are: a
display label, a filter condition, the derived `log_type` expression, a
display-casing entry, and a sidebar icon.
## How to test
- Open a project with Multigres logs and go to the new unified logs view
- Open the Log Type filter and confirm "Multigres" appears as an option
- Select "Multigres" and confirm rows from the `multigres_logs` source
are returned and labeled "Multigres" with the network icon
- Expected result: Multigres logs are filterable and display correctly,
matching the legacy logs behavior
## Notes
Level/severity uses the shared `severity_text` fallback that all
non-HTTP sources rely on. If Multigres rows come back always classified
as success, the OTEL pipeline may not populate `severity_text` for this
source (legacy logs read the level from a JSON `event_message`), which
would need a source-specific level branch.

## Summary by CodeRabbit
* **New Features**
* Added support for the **Multigres** log type in Unified Logs (labels,
icon, and derived filtering/grouping/counting).
* Unified Logs now renders Multigres **event_message** by extracting the
`msg` field from valid JSON, with correct capitalization.
* Unified Logs row click telemetry now recognizes **Multigres**.
* The **Multigres** log type option is hidden when the selected project
is not high-availability.
* **Tests**
* Added/updated unit tests for Multigres event-message parsing and
shared event-message display behavior.

## What
When the unified logs preview is enabled, clicking a chart bar that
links to a logs view now opens **unified logs** (scoped to the service
and time bucket) instead of the legacy logs explorer.
Surfaces updated:
- Homepage project usage charts (`ProjectUsageSectionDeltas`,
`ProjectUsageSection`)
- Observability overview service health table (`ObservabilityOverview`)
— also fixes the API Gateway row and passes the time range via the
`date` param unified logs actually reads
Adds a small `buildUnifiedLogsUrl` helper so the deep-link format
(`filter=log_type:eq:<type>` + `date` epoch-ms range) lives in one
place.
When the preview is off, behavior is unchanged (legacy logs explorer).
Resolves O11Y-2133.

* Added unified logs navigation for project usage and observability
charts.
