Channel open fee control, channels tab in wallet settings, mempool tx
link, and the channel-open async peer-connect race fix. Conflict in
LightningChannels.vue resolved to the branch's extracted
LightningChannelsPanel component, with main's Teleport-to-body modal
fixes and glass-button-warning class (8256fde1) ported into the panel
so they aren't lost. lnd tests 16/16, LightningChannels vitest green.
