fix(status): add -a/--agent and -c/--cloud filter flags to spawn status (#2379)

`spawn status` silently ignored -a and -c flags, showing all servers
regardless. This is inconsistent with `spawn list` and `spawn delete`
which both support these filters.

- Update `cmdStatus` to accept `agentFilter`/`cloudFilter` options and
  pass them to `filterHistory()`
- Update `dispatchStatusCommand` to parse filter flags using the shared
  `parseListFilters` helper (same as list/delete)
- Document filter flags in help text for `spawn status`
- Bump version to 0.15.27

Fixes #2377
