Fix ps ignoring --status filter when combined with -a/--all

[mosquito]

The --status flag was silently discarded when -a was used because the entire status-resolution block was guarded by if not args.all. Changed the default to None so explicit --status is always respected regardless of -a.

Pull request overview

Fixes contree ps incorrectly ignoring an explicit --status filter whenever -a/--all was also provided, ensuring the status filter is always respected.

Changes:

• Change --status default to None so “unset” is distinguishable from an explicitly provided value.
• Update cmd_ps status-selection logic to apply --status regardless of --all, while keeping the previous default filtering behavior when neither is specified.
• Add a regression test covering --all combined with an explicit --status.

Pull request overview

Fixes ps so an explicitly provided --status filter is respected even when combined with -a/--all, aligning CLI behavior with user intent and preventing silent filter drops.

Changes:

• Change --status argparse default to None and apply EXECUTING as the implicit default only when --all is not used.
• Update cmd_ps status-resolution logic so explicit --status always wins over --all.
• Add a regression test covering --all --status <value> request parameter behavior.
