refactor(src/commands): add timeouthandling and internal daemon guard

Adds 2‑second timeouts around D‑Bus interactions and guards against internal daemon self‑calls; refactors command handling to use a consistent async timeout pattern and improves error reporting.

New Features
- Wrap D‑Bus calls with a 2‑second timeout to prevent hangs
- Early‑exit when $LAPCTL_DAEMON_INTERNAL is set to skip self‑calls- Apply consistent timeout usage across all commands

Enhancements
- Unified error handling using the `matches!` macro
- Reduced race conditions in connection establishment

Bug Fixes
- Prevent silent failures when a connection timeout occurs
