fix: add access control to mintEdition and batchMintEditions

[ArshLabs]

Problem

mintEdition() and batchMintEditions() in LensMintERC1155.sol have no access control. Any address can:

1. Mint unlimited editions of any original token
2. Bypass the maxEditions limit
3. Create editions of tokens from devices they dont own

This breaks the core provenance model. LensMint's value prop is that every edition is cryptographically tied to the device that captured the original photo. Without this check that guarantee means nothing at the contract level.

Fix

Added UnauthorizedMinter custom error and restricted both functions to the device address stored in the original token's TokenInfo, or the contract owner.

error UnauthorizedMinter();

if (msg.sender != original.deviceAddress && msg.sender != owner())
    revert UnauthorizedMinter();

Complements PR #4 (ECDSA signature verification). Together these close the two main authorization gaps in the minting flow.

Hello, we don't want only owner to mint the NFT's as owner can create the multiple nft's and share QR amongst others so that they can also mint the NFT. Adding this owner constraint doesn't fit here.
