fix(appview): address review feedback on ATB-37 bootstrap upgrade
- Pass ctx.logger to parseAtUri so malformed roleUris emit structured
warnings at parse time
- Add explicit error log when parseAtUri returns null (data integrity
signal — a stored roleUri that can't be parsed is unexpected)
- Upgrade warn → error in DB failure catch: a failed role lookup during
bootstrap upgrade has the same consequence as the role-not-found path
(firehose will null out roleUri), so both warrant error level
- Add DB failure test for the role lookup catch block
- Add malformed roleUri test (parseAtUri returns null path)
- Add result.created assertions to tests 1 and 2
- Add DB state assertions to all three new bootstrap upgrade tests
