Infer record pickers for record-typed logic function workflow inputs (#21494)

## Context

Logic functions can declare workflow inputs typed as records or arrays
of records (e.g. the People Data Labs enrichment functions), but the
workflow builder rendered those as a plain text input with a variable
picker, which is not usable.

## What this does

- Adds an `objectUniversalIdentifier` link on input schema properties,
so a record-typed input is tied to a workspace object.
- The SDK build infers it from a
`TwentyRecord<'objectUniversalIdentifier'>` marker type in the handler
signature, reading the object's universal identifier straight from the
source; explicit input schemas can still set the field directly.
- The workflow builder renders these inputs as a single record picker or
a record multi-select with the variable picker on the right. Selected
records are stored as record ids; `TwentyRecord<UID>` is a branded
`string`, so the handler signature reflects that it receives ids (a
bound variable resolves to whatever the referenced step produced).
- The multi-select collapses overflowing chips into a `+N` badge
(reusing `ExpandableList`) and its variable picker offers both record
objects and fields.
- Updates the People Data Labs enrichment inputs as the reference
implementation.
