Centralize common code in shared folder

This commit reorganizes the codebase to eliminate duplication between web and mobile frontends by moving all commonly used files to the shared folder.

Changes:
- Moved lib files to shared/lib/:
  * wallet.ts, staking.ts, tiki.ts, identity.ts
  * multisig.ts, usdt.ts, scores.ts, citizenship-workflow.ts

- Moved utils to shared/utils/:
  * auth.ts, dex.ts
  * Created format.ts (extracted formatNumber from web utils)

- Created shared/theme/:
  * colors.ts (Kurdistan and App color definitions)

- Updated web configuration:
  * Added @pezkuwi/* path aliases in tsconfig.json and vite.config.ts
  * Updated all imports to use @pezkuwi/lib/*, @pezkuwi/utils/*, @pezkuwi/theme/*
  * Removed duplicate files from web/src/lib and web/src/utils

- Updated mobile configuration:
  * Added @pezkuwi/* path aliases in tsconfig.json
  * Updated theme/colors.ts to re-export from shared
  * Mobile already uses relative imports to shared (no changes needed)

Architecture Benefits:
- Single source of truth for common code
- No duplication between frontends
- Easier maintenance and consistency
- Clear separation of shared vs platform-specific code

Web-specific files kept:
- web/src/lib/supabase.ts
- web/src/lib/utils.ts (cn function for Tailwind, re-exports formatNumber from shared)

All imports updated and tested. Both web and mobile now use the centralized shared folder.
