feat(web): show ALL flick legends

### Is your feature request related to a problem? Please describe.

I currently use Unexpected Keyboard to type in Shavian. I went to update my Keyman layout to support the newly added flick gestures, but came across a missing fundamental feature.

Here's the Unexpected Keyboard layout I want to recreate:


Here's how it looks on Keyman now:


Notice anything missing? Yes, the flick legends are missing.

I honestly can't believe I have to explicitly say that this is a necessary feature. As an example from another app, here's GODAN layout for Japanese on Gboard:


There are actually 3 hidden shortcuts on the A, I, U, E, and O keys, but all the other swipe legends are always active.

Here's the keypad layout for Japanese on also Gboard:


The key legends on the main 10 keys are hidden, but long-pressing reveals the flick legends. (This method is not workable on Keyman because the same key may have both long-press and flick gestures.)

### Describe the solution you'd like

Add an option that says "Show all flick hints" in Touch Layout > Platform > Edit... > Default hint source
