fix(terminal): init all tabs on load, fix excessive zoom

Use visibility:hidden instead of display:none for inactive terminal tabs
so xterm containers retain their dimensions. This allows all terminals
to initialize independently and prevents fitAddon from miscalculating
cell sizes on zero-height containers.
