Golang Backend and Indexer

[MSghais]

Description

Update indexer of Pixel with the new features located in art_peace.cairo :

• ShieldPixel
• Add the Shield event
• Saved in db the Shield

#[derive(Drop, starknet::Event)]
pub struct PixelShieldPlaced {
#[key]
pub placed_by: ContractAddress,
#[key]
pub pos: u128,
pub shield_type: PixelShieldType,
pub amount_paid: u256,
}

• Add the pixel metadata event
• Create the endpoints and saved the PixelMetadata

PixelMetadata Event:
#[derive(Drop, starknet::Event)]
pub struct PixelMetadataPlaced {
#[key]
pub placed_by: ContractAddress,
#[key]
pub pos: u128,
#[key]
pub day: u32,
pub color: u8,
pub metadata: MetadataPixel,
}

#[derive(Drop, Serde, starknet::Store, Clone)]
pub struct MetadataPixel {
pub pos: u128,
// Color index in the palette
pub ipfs: ByteArray,
pub nostr_event_id: u256,
pub owner: starknet::ContractAddress,
pub contract: starknet::ContractAddress,
}

Hi! I can implement the pixel shield and metadata features. Here's my plan:

ETA: 15-18 hours

• Study existing codebase patterns
• Add DB tables + indexer handlers
• Add API endpoints + testing

Main tasks:

1. Handle new Cairo events (ShieldPixel, PixelMetadata)
2. Store shield/metadata in Postgres
3. Create endpoints to access the data

I'm experienced with backend/DB work but will need some time to get familiar with Go/Cairo specifics. Already reviewed pixel.go and understand the event processing patterns
