## 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.

## What
Cleans up the service health chart labels so they are consistent across
the project homepage usage charts (behind the `newHomepageUsageDeltas`
flag) and the `/observability` service health table. Part of DEBUG-148.
## Changes
- Per-level charts now read `Errors / Warnings / Infos` (the success
series was `Ok` on `/observability` and `Requests` on the homepage).
- Homepage service cards use full-word `Warnings` / `Errors` headers
(was `Warn` / `Err`).
- The `Total Requests` headline keeps the `Requests` wording and its
existing value.
## Not in this PR
- Grouping the API Gateway chart by product. Summing every service's log
levels and labeling it "API Gateway" is not accurate data; real
per-product grouping needs the service-health matview to group API
Gateway requests by product first. Tracked as a follow-up.
- The 30-day interval option mentioned in the thread.
## Testing
- typecheck, prettier, ratchet, and unit tests green in CI.
- Pending manual confirmation in Studio that the tooltips read Errors /
Warnings / Infos on both surfaces.

## Summary by CodeRabbit
* **UI Improvements**
* Updated service health charts to show clearer segment labels for
errors, warnings, and healthy states.
* Refined project usage metrics text to use more user-friendly labels
like “Warnings” and “Errors.”
* Adjusted chart labeling for one usage view so the healthy/OK series is
presented more clearly.

## Problem
We now export components under a subpath in ui-patterns to avoid barrel
files as they slow down every tools (from IDE to linters, etc.) and may
also affect bundles our users have to download.
## Solution
- Remove the UI patterns index file
- Fix invalid impors
