Multi-chain fixes for Axiom and Padre.

• Axiom: the trading widget now appears on Robinhood and BNB tokens.
Axiom moved these to a new page URL format, which DryFlip didn't recognise.
• Axiom: trade history links now open the correct token page on every chain.
• Padre: added full support for Robinhood tokens — the widget now loads and
uses the correct balance.
• Padre: chart markers and background take-profit / stop-loss now work on
Ethereum and Base as well as Solana and BNB.
• PNL cards: fixed the profit/loss amount showing as a blank coloured block
on Robinhood trades.
• Active Trades: the copy button now copies the real token contract address
instead of an internal pool identifier.
