Fix install.sh: build from source instead of requiring pre-built dist

The script previously checked for a dist/ directory and failed with
"Please run this script from the TSMusicBot source directory after
building" — requiring users to manually build before installing.

Now the script:
- Resolves project root from script location (works from any cwd)
- Installs build tools (build-essential/gcc) for native modules
- Runs npm install + npm run build automatically
- Copies built artifacts to /opt/tsmusicbot
- Creates data directory for runtime files
- Adds journalctl command to the help output
