[Oracle] Parse sets lazily to slash importer peak memory (#7217)

Browse source 
* [Oracle] Parse sets lazily to slash importer peak memory

- Add a raw JSON scanner that splits the document into per-set byte ranges
  without materializing the JSON tree
- Keep only the raw document bytes and parse one set at a time in startImport
- Take readSetsFromByteArray by value so the wizard's buffer is moved, not copied
- Clear the retained raw data in releaseSetData()/clear()
- Cover the scanner and lazy parsing with tests

Took 2 minutes

* [Oracle] Fix nesting-depth cap, tolerate unescaped control chars, lazy-parse review fixes
