fix: Rebrand systemd templates, polkit rules, and install scripts

- src/templates/pipedald.service.template — user/group pipedal_d → oppedal_d
- src/templates/pipedaladmind.service.template — WorkingDirectory /var/pipedal → /var/oppedal
- src/templates/pipedal_nm_p2pd.service.template — Description and WorkingDirectory
- src/templates/pipedal_p2pd.service.template — Description and WorkingDirectory
- src/templates/pipedal_p2pd.conf.template — p2p_model_name, manufacturer
- src/templates/jack.service.template — After=pipedald → After=oppedald
- src/templates/*.conf — PiPedal/pipedal-* → OP-Pedal/oppedal-* references
- src/polkit-1/rules/10-pipedal-networkmanager.rules — group pipedal_d → oppedal_d
- install.sh — pipedalconfig/oppedalconfig binary paths
- uninstall.sh — /etc/pipedal, /var/pipedal → /etc/oppedal, /var/oppedal
- run.sh — pipedald → oppedald, /etc/pipedal → /etc/oppedal
