refactor: extract shared helpers and reduce duplication

Backend:
- validateDatasetName now throws BadRequestException directly,
  eliminating the try/catch wrappers at both call sites
- Extract failOnDuplicateDatasetName[T] helper that catches SQLState
  23505 and maps to BadRequestException, replacing two identical
  6-line catch blocks
- Use jOOQ's built-in e.sqlState() instead of the manual
  Option(e.getCause).collect dance
- Hoist regex to a class-level val (compiled once, not per call)
- Merge redundant null/empty check into the regex check (regex +
  quantifier already rejects empty strings)

Frontend:
- Export validateDatasetName() from dataset.service.ts as the single
  source of truth for the name rule (regex + max length + error message)
- All three components now call the shared validator instead of
  inlining the regex, magic number 128, and error string
