feat: complete Phase 1 foundation hardening + three-mode UI design doc

Phase 1a — Gradient Removal:
- Replaced all gradient-button/gradient-card with glass-button/path-option-card
- Removed banned gradient CSS classes

Phase 1b — Security Hardening:
- SecretsManager: AES-256-GCM encryption (core/security)
- electrs_status: credentials from env vars instead of hardcoded
- port_manager: RwLock proper error handling (no unwrap)
- Pinned all 11 :latest manifest images to specific versions
- parmanode converter: pinned inferred image versions

Phase 1c — Code Quality:
- Split rpc.rs (1795 lines) into 6 handler modules (auth, node, container, package, peers)
- Removed sideload code (UI, store, RPC client, 3 doc files)
- Fixed body background flash on logout/refresh
- Replaced 30 TypeScript `any` types with proper types
- Deleted HelloWorld.vue, removed TODO comments
- Added set -euo pipefail to all shell scripts
- Made deploy script verbose with timestamps and elapsed time

Also adds:
- CLAUDE.md project guide
- docs/three-mode-ui-design.md — design spec for Easy/Pro/Chat UI modes
- OnlineStatusPill component
