fix(ci): pin ttyd 1.7.7 via mise — fixes prefix e2e failures

CI installed ttyd 1.7.4 from apt which bundles an older xterm.js.
The prefix button's async handler (sendText → openComboPicker) broke
silently, causing all 8 prefix Playwright tests to fail.

Pin ttyd in mise.toml so CI and local use the same version.

-remobi uses standard ttyd flags (`--writable`, `-t`, `-i`) and should work with any recent ttyd release.
+Tested with ttyd 1.7.7. Older versions (e.g. 1.7.4 from Ubuntu apt) may have xterm.js incompatibilities.
