[BUG] Toggling 'Expose Private Websocket' and 'Expose Public Websocket' switches them off/on before clicking Update

[BenGWeeks]

Description

In the Settings dialog, toggling the "Expose Private Websocket" and "Expose Public Websocket" checkboxes immediately changes the setting state before the user clicks the "Update" button.

Expected Behavior

The toggle changes should only be applied after clicking the "Update" button, allowing users to review their changes before committing them.

Actual Behavior

The settings are applied immediately when the toggle is clicked, before the user confirms by clicking "Update".

Steps to Reproduce

1. Open the Nostr Proxy extension
2. Click the Settings icon
3. Toggle either "Expose Private Websocket" or "Expose Public Websocket"
4. Observe that the setting changes immediately without clicking "Update"

Consider renaming "Expose" to "Enable" or just "Private websocket" and "Public websocket".
Consider adding an intro paragraph/sentance explaining what these settings do.
