- Fee selector on channel open: Standard (~6 blocks) / Medium (~3) /
Fast (next block) presets, or custom target confirmations / sat/vB;
backend validates and passes target_conf / sat_per_vbyte to LND
- Extract channel management into LightningChannelsPanel, reused by the
LND channels page and a new Channels tab in the Wallet Settings modal
- Funding tx link on each channel card opens the node's mempool app at
/tx/<txid>
