✨ feat(device): add rename & delete actions to branch switcher (#15774)

Hover a branch row in the branch switcher to rename or delete it. Wires
new renameGitBranch / deleteGitBranch operations through both transports
(Electron IPC for the local machine, device.* TRPC RPCs for remote/web),
mirroring the existing checkoutGitBranch / revertGitFile stack.
