fix: resolve CI failures — ruff, mypy, and ShellCheck

ruff: fix import order, Dict→dict, and unused variable in discord_bridge_service.py

mypy: add types-requests to test deps to resolve import-untyped warnings;
add per-module ignore_errors overrides for modules not yet brought up to
strict typing standard

ShellCheck: remove unused vars (SC2034) in install-service.sh and
uninstall-service.sh; split local declare/assign (SC2155) in
install-service.sh and restart_viewer.sh; replace ls|grep (SC2010) with
glob loops in docker-setup.sh; capture $? immediately after heredoc (SC2320)
