Jack 67c3e73d70 feat: migrate DELETE /api/v1/datasets/:dataset_id/documents to Go (#15577) ...

## Summary

Migrate the batch document deletion endpoint from Python to Go. Two
modes supported: explicit `ids` list and `delete_all`.

## Changes

| File | Change |
|------|--------|
| `internal/dao/file2document.go` | Add `GetByDocumentID`,
`DeleteByDocumentID` |
| `internal/dao/file2document_test.go` | 5 new tests |
| `internal/dao/kb_test.go` | 2 new tests (`DecreaseDocumentNum`) |
| `internal/service/document.go` | Add `deleteDocumentFull` +
`DeleteDocuments`, refactor `DeleteDocument` |
| `internal/service/document_test.go` | 10 new tests |
| `internal/handler/document.go` | Add `documentServiceIface` +
`DeleteDocuments` handler |
| `internal/handler/document_test.go` | 7 new tests |
| `internal/router/router.go` | Register `DELETE /:dataset_id/documents`
|
| `cmd/server_main.go` | Support `RAGFLOW_DICT_PATH` env var |
| `internal/binding/rag_analyzer.go` | Use `-lpcre2-8` dynamic linking |
| `internal/dao/database.go` | Skip Error 1091/1138 during migration |
| `internal/service/llm.go` | Fix vet warning |

## Per-document cleanup

- Delete tasks from DB
- Hard-delete document + decrement KB counters
- Delete chunks from document engine (nil-guarded)
- Delete metadata from document engine (nil-guarded)
- Remove file2document mapping + file record + storage blob

## Test Results

**24 unit tests all passing** (7 DAO + 10 service + 7 handler) using
SQLite :memory: + gin.TestMode.

See [test report](docs/test_report_delete_documents.md) for manual
integration test results.
