## Summary

Backport the 2.6 partial update op series to `hotfix-2.6.16`:

- support `ARRAY_APPEND` and `ARRAY_REMOVE` partial update ops for Array
fields
- expose `fieldOps` through REST upsert
- preserve existing Array rows when an op payload row is null

## Target branch

Base branch: `hotfix-2.6.16`

## Cherry-picks

- `5849977c408be2abd063d13c318e970bb4515f06` from
[#49328](https://github.com/milvus-io/milvus/pull/49328)
- `017ee8e5d97ec891c442489b1354b60676ca3b15` from
[#49724](https://github.com/milvus-io/milvus/pull/49724)
- `4e10473389843ff2cedc1911083af5a93fa83ec6` from
[#49763](https://github.com/milvus-io/milvus/pull/49763)
- `824c642c71154952bf70eaaf7b57cbcd7d08e67f` backports the applicable
WAL test/recovery stabilization from
`73dc8d4034fd352f5c69fd47266fccc062704feb` /
[#49698](https://github.com/milvus-io/milvus/pull/49698) after omitting
newer rate-limit API changes that do not exist on `hotfix-2.6.16`

The partial update cherry-picks applied cleanly on top of
`milvus/hotfix-2.6.16`.

## Additional revert

- `2753c8defc7a860446d1f5f76b11a50c3cc71550` reverts
  `8ae21f715094abc92e00369e89a7208681eecfed` to restore the 2.6.16
build environment image version after CI reported Conan 2.x in the newer
  image.

## Validation

- `git diff --check milvus/hotfix-2.6.16...HEAD`
- attempted targeted Go test for
`internal/streamingnode/server/wal/adaptor`, blocked locally because
this worktree lacks `rocksdb.pc` and `milvus_core.pc`

PR CI is the validation gate for this backport.
