### Which issue does this PR close?
Closes #2011
### Rationale for this change
The History Server plugin currently crashes during initialization when the
`AuronBuildInfoUIData` record is missing from the KVStore. This causes
applications without BuildInfo events to either fail plugin initialization or
show no Auron tab.
### What changes are included in this PR?
1. **AuronSQLAppStatusStore**: Changed `buildInfo()` to return
`Option[AuronBuildInfoUIData]`, catching `NoSuchElementException` and other
exceptions to return `None` instead of throwing
2. **AuronSQLHistoryServerPlugin**: Removed the null check and always create
the Auron tab, letting the UI handle empty state
3. **AuronAllExecutionsPage**: Added `buildInfoSummary()` method to handle
`Option[AuronBuildInfoUIData]`:
- `Some`: displays BuildInfo table as before
- `None`: shows user-friendly message "Auron build information is not
available for this application."
### Are there any user-facing changes?
Yes. When BuildInfo is not available:
- Before: Plugin initialization fails or no Auron tab appears
- After: Auron tab displays with a clear warning message explaining
BuildInfo is unavailable
### How was this patch tested?
- Existing unit tests pass
