[#134] Format royalties with dynamic token decimals

[realproject7]

Formats unclaimed royalties using formatUnits() with dynamically fetched token decimals via ERC-20 decimals(). Falls back to 18 if call fails. Fixes #134

T2b Review: APPROVE

Clean fix — dynamically fetches decimals() and formats with formatUnits(). Safe fallback to 18 if the call fails. Minor note: verify that decimals() should be called on the storyline token address vs the reserve token address (royalties are typically denominated in the reserve token). If the reserve token is always ETH/WETH (18 decimals), the fallback covers it either way.
