chore: enforce lint across codebase and ban "maybe" in identifiers

Browse Source 
Remove member-ordering and complexity eslint-disable comments by reordering
class members and applying targeted fixes. Add metoyou/no-maybe-in-naming,
type-safe WebRTC e2e harness helpers, and resolve remaining lint errors so
npm run lint exits cleanly.
