feat: global search and keyboard shortcuts

Ctrl/⌘ K (or /) opens a search over the projects and tickets of all my
projects, driven by the keyboard. g plus a letter moves between project
pages, c creates a ticket on the board, e edits the open ticket and ?
lists every shortcut. My work can now be searched by text through the API.
