feat: Implemented Openzeppelin ERC1155 sticker and also its community usage system to

[Oluwaseyi89]

📋 Overview

This PR implements the core foundation for the community sticker system, addressing both Issue #35 (Core Sticker Contract) and Issue #36 (Usage System & Limits). The implementation establishes a complete ERC1155-based sticker ecosystem with creation, management, and usage tracking capabilities.

🎯 Features Implemented

✅ Core Sticker Contract (#35)

ERC1155 Integration: Full OpenZeppelin ERC1155Component implementation for fungible sticker tokens

Sticker Creation: Open creation system with automatic token minting and unique ID generation

Metadata Management: Comprehensive on-chain storage for name, description, tags, category, creator, and content hash

Creator Tracking: Complete creator attribution system with immutable ownership records

Validation System: String length limits and non-empty checks for all metadata fields

Query Functions: Full suite of read operations including:

get_sticker_metadata() - Retrieve complete sticker details

get_stickers_by_creator() - List all stickers by creator address

get_total_sticker_count() - Global sticker counter

get_sticker_creation_timestamp() - Immutable creation timestamps

✅ Community Sticker Usage System (#36)

Daily Limit System: Configurable free usage limits (default: 10 uses/day)

Usage Tracking: Per-user daily usage counting with automatic daily resets

Payment Integration: Ready framework for excess usage payments (ERC20 integration ready)

Event System: Comprehensive events for usage, payments, and daily resets

Admin Controls: Configurable limits, costs, and treasury address management

🏗 Technical Architecture

Core Sticker Contract (StickerContract):

OpenZeppelin ERC1155Component with Ownable access control

Structured metadata storage with validation

Creator-to-sticker mapping system

Sequential ID generation with global counter

Usage System (CommunityStickerUsage):

Daily usage tracking with (user, day) tuple storage

Configurable limits and payment parameters

Event-driven architecture for monitoring

Admin-controlled configuration

📊 Storage Optimization

Efficient Metadata: Fixed-length string limits for gas optimization

Minimal Mapping: Optimized storage patterns for frequent read/write operations

Scalable Design: Support for unlimited stickers and users

🧪 Acceptance Criteria Met
