fix(array-operation): start encrypted array on Enter in passphrase field (OS-462)

[elibosley]

Summary

On the Array Operation page, when starting an encrypted array you must type the passphrase and then click the Start button — pressing Enter in the passphrase field does nothing. This adds Enter-to-start so the passphrase field behaves like a normal login form.

Changes

• Added a small submitOnEnter(event) helper in ArrayOperation.page that, on Enter, clicks #cmdStart only when it is enabled.
• Wired onkeydown='submitOnEnter(event)' onto the Passphrase and Retype passphrase inputs.

Because it just clicks the existing Start button, it inherits all current validation: the button stays disabled until the passphrase is non-empty (and matches the retype field when shown), so Enter can't bypass any checks or fire while the array isn't ready to start. The keyfile flow is unaffected.

Test plan

• Stopped, encrypted array → focus the Passphrase field, type a valid passphrase, press Enter → array starts (same as clicking Start).
• Empty passphrase + Enter → nothing happens (button still disabled).
• New-key / reformat case with Retype passphrase → Enter only starts once both fields match.

Summary by CodeRabbit

• New Features
  • Added Enter-key support in the encryption passphrase and retype passphrase fields, so pressing Enter behaves like clicking the start button.
  • When the retype field is visible, Enter advances focus to the correct retype input; otherwise it initiates the operation automatically.

Linear

• OS-462

Walkthrough

A new submitOnEnter(event) JavaScript function is added to ArrayOperation.page. It intercepts Enter keypresses, prevents default form submission, and either triggers a click on the cmdStart button if it exists and is not disabled, or advances focus to the retype-passphrase field when in the set-new-passphrase state. The passphrase and retype-passphrase input fields are updated to call this function via onkeydown.

Changes

Enter-key submit for encryption passphrase inputs

Layer / File(s)	Summary
submitOnEnter helper and input wiring emhttp/plugins/dynamix/ArrayOperation.page	New submitOnEnter(event) function prevents default Enter behavior, clicks cmdStart when present and enabled, or advances focus to retype field when in set-new-passphrase state; passphrase and retype-passphrase inputs gain onkeydown="submitOnEnter(event)".

🐇 Tap tap tap goes the key,
No more clicking, fingers free!
Enter pressed on passphrase true,
The array starts—hop right through!
A rabbit's shortcut, neat and new~ 🗝️
