## Summary
Fixes#17667
- **Root cause**: `ActivityQueryResultGetterHandler` called
`JSON.parse()` on the `blocknote` field and assumed the result was
always an array. When the stored value was valid JSON but not an array
(e.g., `"{}"`), `blocknote.map()` crashed with `blocknote.map is not a
function`, breaking the entire notes page.
- **Fix**: Replaced the object-level `ActivityQueryResultGetterHandler`
(hardcoded for `note`/`task` only) with a generic field-level
`RichTextV2FieldQueryResultGetterHandler` that safely parses blocknote
JSON with `Array.isArray` validation and gracefully skips malformed
values instead of crashing.
- **Bonus**: The new handler works for **all** objects with
`RICH_TEXT_V2` fields (not just `note`/`task`), following the same
pattern as the existing `FilesFieldQueryResultGetterHandler`.
## Changes
| File | Change |
|------|--------|
| `rich-text-v2-field-query-result-getter.handler.ts` | New field-level
handler with safe blocknote parsing |
| `common-result-getters.service.ts` | Register new handler, remove
`note`/`task` object handlers |
| `activity-query-result-getter.handler.ts` | Deleted (replaced by
field-level handler) |
| `rich-text-v2-field-query-result-getter.handler.spec.ts` | 9 tests
covering all edge cases |
## Test plan
- [x] Unit tests pass (9 tests covering: null blocknote, non-string
blocknote, invalid JSON, non-array JSON like `"{}"`, no images, external
URLs, internal URLs, multiple fields)
- [x] Lint passes (`lint:diff-with-main`)
- [x] Typecheck passes
