Subject: [PATCH 2/2] fix: make timestamp optional in RampEphemeralEntry, use
 optional chaining in sort, align test batch size

- Make `timestamp` optional in `RampEphemeralEntry` for backwards compatibility with entries from older app versions
- Use optional chaining (`?.timestamp ?? 0`) in eviction sort to guard against null/corrupt localStorage entries; legacy entries without a timestamp get value 0 (treated as oldest)
- Update `expectedDeleteBatchSize` in base.service.test.ts from 500 to 5000 to match the production `EXPIRED_QUOTE_DELETE_BATCH_SIZE` constant
