[PM-15943] - fix extension flicker when filling in a password

📔 Objective

This PR fixes an issue where, upon autofilling, the extension UI would quickly reload before closing. The cause was the call to await this.cipherService.updateLastUsedDate(options.cipher.id); which was causing the service to re-emit values and the consuming components to re-render. Doing the update in the background avoids the UI flicker but still ensures the last used password is still top of the autofill suggestion list.
