Remove status and disk helpers left unused by the selector removal (#2651)

Stacked on #2649 (base commit dcd409f9da). Deleting
`infrastructureSelectors.ts` there removed the only production caller of
three more exports. `getInfrastructureSystemIdentitySortLabel` is
removed in the prose-sweep change. This removes the other two:

- `STATUS_SORT_ORDER` in `utils/status.ts`, plus the test that only
pinned its contents.
- `getResourceDiskSummary` in `utils/format.ts`, plus its two tests and
the now-unused `Resource` type import.

Neither is used inside its own module. The helpers
`getResourceDiskSummary` relied on (`normalizeDiskArray`,
`NormalizedDisk`) keep their other callers, and neither file has a
subsystem owner or contract entry.

## Verification

- Rollup was already tree-shaking both exports, so the production build
is byte-identical to the #2649 build (SHA-256 of every file in `dist`).
- `tsc`, eslint and the `src/utils` suites pass, apart from the six
`agentInstallCommand.test.ts` PTY lifecycle cases that always fail on
the Mac.
- Browser receipt `b5563a7bd4ae414b.json`, recorded on that build: the
Proxmox Workloads I/O emphasis and the Docker drawer change-history
facet chips, at 1920, 1440 and 390 wide.

It merges cleanly with current main and with #2650.
