Refactor lint tslint

[r1n04h]

Note

Adds GitHub Actions CI using Bun for type-checking, linting, and tests; adds a TypeScript check script; strengthens assertion and event typings; and tidies LoginPage styles.

• CI:
  • Add workflow .github/workflows/ci.yml with jobs for TypeScript type-check (bun run tslint), Biome check (bun run check), and tests (bun run test).
  • Add "tslint": "tsc --noEmit" script in package.json.
• Types/Backend:
  • Refactor src/assert.ts to define Assert interface and add precise assertion signatures (asserts value).
  • Update src/spark-service.ts event listener to use updatedBalance: bigint and cast in log.
• Frontend:
  • Clean up styles in src/client/components/LoginPage.tsx (remove inline keyframe defs).

Bug: Missing shake keyframe animation definition causes broken animation

The @keyframes shake animation definition was removed from the inline styles, but the element still references animation: 'shake 1.5s infinite'. Since shake is not defined anywhere else in the codebase (unlike pulse which exists in public/index.html), the shake animation on the "⚠️ Important:" warning label will not work at all.

Lines 637 to 639 in 3dfecc5

	fontWeight: '600',
	animation: 'shake 1.5s infinite',
	display: 'inline-block',

Bug: Pulse animation behavior changed after removing inline keyframes

The @keyframes pulse definition removed from inline styles had box-shadow and subtle scale animations, but the pulse keyframe in public/index.html only does a different scale animation (1 to 1.05). The warning box still references animation: 'pulse 2s infinite', so it will now display a different visual effect than originally intended.
