fix(tokens): resolve token via tokenCoordinator when stateFlow race loses

The ConfirmPhantomTransaction and Coinbase purchase handlers read
stateFlow.value.tokenWithBalance?.token synchronously. After the
amount-entry refactor the async combine flow that populates
tokenWithBalance can lose the race, leaving the snapshot null.

Extract resolveToken() that falls back to
tokenCoordinator.getTokenMetadata(mint) (memory -> Room -> network)
when the flow hasn't delivered yet.

Also bumps phantom-connect-kmp 2.0.2-1.0.0 -> 2.0.2-1.0.1.
