Browser autofill: fill the login matching the username already typed (keyboard shortcut)

Code Contribution Proposal

I'd like to add an option to the browser extension that makes the autofill keyboard shortcut (Ctrl+Shift+L) fill the login matching the username you have already typed, instead of always starting from the first / last-used entry. Happy to build it myself if the team is open to it.

This builds on #377 (repeat shortcut presses cycle through logins). One of the comments there suggested pretty much this - check what is already in the field and pick the account that matches. On sites where I have a few accounts, the shortcut fills one of them and I have to keep pressing to get to the right one. If I have already typed part of my username, the extension could just pick the correct login the first time.

Proposed behaviour

• A new Autofill setting, off by default: "Match the login to the typed username".
• When it is on and I press the shortcut on the page's top frame, the extension reads what is in the focused username field and fills the login whose username starts with that text. An exact match wins over a partial one; ties fall back to the usual last-used ordering.
• If nothing is typed, or nothing matches, it behaves exactly like today.
• Pressing the shortcut again still cycles, so the Cycle logins when using autofill shortcut multiple times #377 behaviour is unchanged.

Scope and safety

It only reads the field on a genuine top-frame shortcut press, so a subframe can never influence which login is chosen. It never touches password fields (text / email / tel only), the read value is length-capped, and the automated auto-submit-login flow is left out. The whole thing is opt-in and off by default.

Status

I have this working locally with unit tests and can open the PR once the approach is agreed. I am also fine putting it behind a feature flag if that is preferred.
