fix(calendar): use [/] for year navigation instead of ctrl+shift+h/l

Bubbletea v1 can't distinguish ctrl+shift+letter from ctrl+letter in
most terminals, so ctrl+shift+h/l silently did nothing. Switched to
[/] which works everywhere and follows the escalating-jump pattern
(h/l day, H/L month, [/] year).
