amyboardweb: use web.patch + .patch boot execution

[bwhitman]

Summary

• rename patches.txt to web.patch and add other.patch
• execute all *.patch files on boot for hardware and web
• remove knob-state localStorage restore/write path for web
• on web, restore knobs from patch source via set_knobs_from_patch(...)
• keep web.patch as single source of knob state and rewrite it on knob changes
• run env.py after patch execution on web boot (matching AMYBOARD order)
• initialize default patch-1 state on fresh boot when web.patch is missing/uninitialized

Validation

• node --check on updated web JS files
• python3 -m py_compile on updated Python files
• make in tulip/amyboardweb
