Jason ad8bdf16ae fix: preserve Codex model catalog on live read of active provider
Editing the currently active Codex provider triggered `read_live_settings`,
which returned only { auth, config }, omitting `modelCatalog`. The form's
mapping table then initialized to empty, and a subsequent save wiped the
DB's `modelCatalog` field — silently destroying user-configured model
mappings after every CC Switch restart.

The mappings already live on disk as a projection in
`~/.codex/cc-switch-model-catalog.json` (pointed at by `config.toml`'s
`model_catalog_json`). Reverse-parse that file so live reads return the
same shape the save path writes.

- Add `read_codex_model_catalog_simplified_from_live` to recover
  `{ model, displayName?, contextWindow? }` entries from the catalog file.
- Skip user-managed external catalogs (filename != cc-switch-model-catalog.json)
  so we don't downgrade their richer structure to the simplified table.
- Squash display_name == slug and context_window == default (config's
  `model_context_window`, or 128_000 fallback) so blank inputs round-trip
  back to blank instead of materializing fallback values in the UI.
- Collapse all failure modes (missing file, parse error, no matching
  field) to Ok(None) so the editor stays openable when the projection
  file is absent or corrupt.
- Wire the new function into `read_live_settings`'s Codex branch.
- Cover the new pure helpers with 7 unit tests in codex_config::tests.
