refactor: rename internal promptId/PromptId to jobId/JobId (#8730)

## Summary

Rename all internal TypeScript usage of legacy `promptId`/`PromptId`
naming to `jobId`/`JobId` across ~38 files for consistency with the
domain model.

## Changes

- **What**: Renamed internal variable names, type aliases, function
names, class getters, interface fields, and comments from
`promptId`/`PromptId` to `jobId`/`JobId`. Wire-protocol field names
(`prompt_id` in Zod schemas and `e.detail.prompt_id` accesses) are
intentionally preserved since they match the backend API contract.

## Review Focus

- All changes are pure renames with no behavioral changes
- Wire-protocol fields (`prompt_id`) are deliberately unchanged to
maintain backend compatibility
- Test fixtures updated to use consistent `job-id` naming
