fix(apps/amm): match swap holdings on the configured id encoding

Moving the token list app-side (readTokensConfig) dropped the module
tokenList()'s base58->hex normalization, so a token's definitionId now
reaches the swap view in whatever encoding TOKENS_CONFIG uses — base58 in
practice. The swap account selector filtered holdings on the hex
definitionIdHex field using that value, so a base58 id matched nothing and
every token showed "No funds", blocking swaps.

Make the selector encoding-aware: a 64-char hex id filters definitionIdHex,
otherwise the base58 definitionId. tokenHoldings already emits both encodings
per holding, so this matches whichever the config uses, needs no app-side
base58 decoder, and mirrors how the liquidity view already filters. The swap
quote/submit path already normalizes base58->hex in the module, so nothing
else changes.
