[Node] Add ipfsQuote nodeCall endpoint

[tcsenpai]

Repository: Node (this repo)

Implement ipfsQuote nodeCall to return cost estimates without transaction.

Files to create/modify

• src/libs/network/routines/nodecalls/ipfs/ipfsQuote.ts - New file
• src/libs/network/routines/nodecalls/ipfs/index.ts - Export new handler

Implementation

export async function ipfsQuote(args: { fileSize: number, operation: 'add' | 'pin' }): Promise<RPCResponse> {
    const { fileSize, operation } = args
    const sender = // get from request context
    const isGenesis = await isGenesisAccount(sender)
    const usedFreeBytes = await getUsedFreeBytes(sender)
    
    const costBreakdown = calculatePinCost(fileSize, isGenesis, usedFreeBytes)
    
    return {
        result: 200,
        response: {
            cost_dem: costBreakdown.finalCost,
            file_size_bytes: fileSize,
            is_genesis_rate: isGenesis,
            breakdown: costBreakdown
        },
        require_reply: false,
        extra: null
    }
}

Register in manageNodeCall.ts

Add case for "ipfsQuote"
