perf(server): index updateId on asset_face, stack and workflow (#32432)

asset_face, stack and workflow were the only tables with an updateId
column but no index on it. Face and stack sync (AssetFacesV1/V2,
StacksV1, PartnerStacksV1) filter and order on updateId, so every mobile
sync seq-scanned every face on the instance and walked all of the user's
(or partners') stacks, even when nothing had changed. workflow isn't
synced; it gets the index for consistency.

Incremental sync with nothing changed, PG 14:

| query                              | before   | after    |
| ---------------------------------- | -------- | -------- |
| assetFace.getUpserts (425k faces)  | 33-37 ms | 0.15 ms  |
| stack.getUpserts (6k stacks)       | 0.8 ms   | 0.004 ms |
| partnerStack.getUpserts (6k)       | 0.6 ms   | 0.007 ms |

The face scan grows with the instance's face count (~10x that at 4M
faces); the stack one with the user's stack count.
