keeps: permalinks for the mint modal + link Token #N to objkt
/kept/\$code and /unkept/\$code now open the respective gallery tab and
auto-open the mint modal for that piece. Uses the existing pending-deep-link
pattern (pendingMintModalCode) and resolves against allCodes once the index
renders. openMintModal pushes history entry, closeMintModal restores tab
root, popstate keeps modal state in sync with nav. Distinct from the bare
/\$code market-detail permalink so both behaviors coexist.
Also lands the small pre-existing UX tweak in the kept index: the Token #N
chip is now an anchor pointing at objkt.com/tokens/{contract}/{tokenId},
with an underline-on-hover style and event.stopPropagation so clicking it
doesn't also open the mint modal.
