[Wave 6: Tags] Support Tag in Bill Split

[puneetlath]

Just like we did in #27936 we should add Tag support for the bill split flow. Meaning:

• tag can be selected
• tag is optimistically set for the bill split and resulting expense
• tag is sent to the API as part of the splitBill API call

Hi, I’m Michael (Mykhailo) from Callstack and I would like to work on this issue.

[rezkiy37]

@puneetlath, can I implement viewing/editing a tag in the scope of this issue? Like it was for categories here - #28628.

[puneetlath]

Yes please. Let's use this issue to bring feature parity for tags on bill split to whatever we do for categories.

The PR - #31647 - is being reviewed internally now. Opening soon 🙂
