* MM-68076 Chunk bulk INSERTs to respect PostgreSQL 65,535 parameter limit (#35761)
PostgreSQL's wire protocol uses a 16-bit integer for parameter count,
causing bulk imports to fail when multi-row INSERTs exceed 65,535
parameters. Add a generic chunkSlice helper that splits rows into
sub-batches capped at 50,000 parameters, and apply it to
saveMultipleMembers (channel), SaveMultipleMembers (team), and
SaveMultipleMemberships (thread). Normal operations (< 3,333 rows)
remain a single INSERT with negligible overhead.
Wrap all chunked INSERT loops in transactions so multi-chunk batches
are atomic — previously channel and team member inserts could leave
partial data if a later chunk failed. Add threadMembershipSliceColumns
helper so thread membership chunk size is derived dynamically.
Includes integration tests for multi-chunk insertion and rollback
verification for channel members, team members, posts, and groups.

With some neat generics, I was able to refactor
the scanning to a util function. I used it to
refactor 3 places and also removed an unnecessary method.
Claude was quite good here.

```release-note
NONE
```
* Moved some common SQL function tu public utls as they are used in plugins
* goimported file
* Added tests
* Created sub-package
* MOved SetupConnection to public sql utils
It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
