feat: KaizenIcons system — Lucide base, full Material Icons migration

Introduces a centralized icon registry (ui/icon/KaizenIcons.kt) that
decouples every UI component from the underlying icon library. All 10
source files migrated from Material Icons Rounded to KaizenIcons backed
by Lucide (1.5px stroke, same library as the web frontend).

Architecture:
- KaizenIcons object with semantic getters (Send, Lock, Brain, etc.)
- Grouped by function (Navigation, Chat, Modes, Files, Settings, etc.)
- Custom brand section ready for hand-drawn SVG overrides
- One-line swap: change the getter, every usage updates
- Zero Material Icon imports remaining in app source
