feat!(backend, website): add a new backend endpoint to get organism for an accession

[anna-parker]

resolves #6265

Generated with claude CLI

Backend: New endpoint GET /get-details

Given a list of accession and/or accessionVersions return details such as isRevocation and organism. This allows us to e.g. know which organism an accession belongs to without querying every LAPIS instance. Currently LAPIS is configured on an organism level and cannot perform such queries, if LAPIS becomes able to do this we can always remove this endpoint.

New files:

• SearchController.kt — top-level controller (no organism prefix) with the new endpoint

Modified files:

• SubmissionTypes.kt — added AccessionVersionWithOrganism data class (accession, version, organism, isRevocation,
  submittedAt as unix timestamp)
• SubmissionDatabaseService.kt — added streamSequenceEntryVersionsForAccessions() that queries sequence_entries_view
  for released entries matching the given accessions/accession-versions
• SequenceEntriesView.kt — added accessionIsOneOf() helper method

Endpoint behavior:

• ?accessionsOrAccessionVersions=LOC_000S01D → returns all released versions of that accession
• ?accessionsOrAccessionVersions=LOC_000S01D.1 → returns that specific released version
• Only returns APPROVED_FOR_RELEASE entries (no auth required)
• Returns NDJSON, sorted by accession then version
  ### Website: Use backend instead of all-LAPIS queries

findOrganismAndData.ts (details page): Instead of querying all LAPIS instances in parallel, now calls backend once to
get organism, then calls only the correct LAPIS instance. The "no version" redirect case is handled directly from the
backend result (finds max version).

getVersionsData.ts (versions page): Instead of querying all LAPIS instances, calls backend once to get organism, then
queries only that organism's LAPIS for version history.

SeqSetRecordsTableWithMetadata.tsx (seqsets): Instead of querying all LAPIS instances in parallel for each record,
calls backend once to get organism for all accessions, then queries only the relevant LAPIS instances (one per
distinct organism in the seqset).

backendClient.ts — added getSequenceEntryVersions() method that parses the NDJSON response.

backend.ts — added accessionVersionWithOrganism Zod schema and AccessionVersionWithOrganism type.

I'll analyze this and get back to you.

I wonder if I should actually move this to a new file called SearchService.kt?
