refactor(tabs): rename js action origin to programmatic-js

Align the public `actionOrigin` enum value with the Obj-C/codegen
naming. `'js'` was ambiguous; `'programmatic-js'` makes it explicit
that this origin covers JS-driven navigation requests delivered via
the `navStateRequest` prop, distinct from a generic "JS" label.

Updates the TS public type and both codegen specs, the Kotlin enum
(`JS` → `PROGRAMMATIC_JS`) and its `toString()` mapping, and the
iOS conversion helper to return the codegen-generated
`ProgrammaticJs` C++ case (RN codegen converts `'programmatic-js'`
kebab-case to `ProgrammaticJs` PascalCase).
