Add automatic Windows and controller startup

[Mamat79]

What changed

• adds two independent startup options: launch Controller Studio with Windows in the notification area, and automatically connect the selected real-time controller
• retries EC4 auto-connection silently while MIDI ports become available during server startup
• shows a localized EC4 waiting screen until LiveProfessor starts sending OSC feedback
• makes the Live/MIDI/OSC settings buttons fully visible in French and English
• removes the Windows startup entry during uninstall
• updates the bilingual README, changelog and both PDF manuals without changing the V.2026.4 version number

Why

A LiveProfessor server should recover after a Windows restart without requiring a manual click on Start, while keeping Windows startup and controller connection separately configurable.

Validation

• python -m pytest -q — 232 passed
• python -m compileall -q src
• git diff --check
• packaged EXE content inspection passed
• installed packaged smoke test returned exit code 0
• visual QA confirmed the startup controls and the full EC4 settings button row

Reset LiveProfessor feedback when MIDI reconnects

After any OSC packet has been received, _liveprofessor_feedback_received remains true for the lifetime of the runtime. If the EC4 later disconnects and reconnects after LiveProfessor has stopped, this block clears only the displayed-wait flag, so _finish_startup_banner() immediately restores stale parameters rather than showing the new waiting screen. Reset the feedback state and request fresh Companion feedback for each new MIDI connection.
