feat(developer): keep Virtual Key Identifier dialog open on Insert

fix(ios): reset context when osk is resized

fix(android/engine): Use fixed sizes for preview keys

fix(developer): Add Wordlist button now copies into source folder

fix(web): track load error detail

Fixes #5063.

It can be useful to be able to insert multiple keys into the active
keyboard source file. With this tweak, the dialog no longer closes with
the Insert button, only with the Close button.

Fixes #2185.

If a wordlist file is not in the same folder as the .model.ts file,
Keyman Developer will now ask the user if they want it copied into the
folder.

Also minor fix: if the user deletes a row in a wordlist, it marks the
file as modified.

Also very minor: the initial folder for the Add Wordlist dialog is now
the same as the .model.ts file.

This is a follow-up for #6331. We still did not have enough detail to
be able to trace the root cause of the load errors. This adds a little
more diagnostics.

feat(oem/fv/ios): Dictionary Support

fix(android/engine): Clear WebView cache on package install

Fixes #4854.

Adds some intelligence to the drag + drop integration with the Touch
Layout Editor, so that we always drop a character onto a key cap, we
always drop a code onto a ID field, and can drop both character + code
together (if the key id is T_new_..., or holding Ctrl key).

Hovering over any key for 0.25 sec while dragging will select that key.
You can then continue dragging down to the subkey array and drop onto
any of those keys. Note that you do not need to hover for 0.25 sec
before you drop onto a key -- the drop operation will select the key
under the cursor when dropping.

Double-clicking will update the selected key or subkey; Ctrl will do
both the key cap and the ID.

Fixes #6258.

While this was done in code as a global override, probably following
Apple stylistic changes, it is better to leave this to the keyboard
developer to decide on.
