Add Color-Coding for Priority/Sender Emails in Verse Webmail

Verse is missing the ability to color-code emails in the inbox based on priority, sender, or other specific criteria.

In the HCL Notes client, users frequently use color-coding rules to highlight emails from specific individuals (like a direct manager or VIP client) or emails marked as high priority. In Verse, the inbox presents a uniform color palette, making it difficult for users to visually triage their incoming mail and immediately spot critical communications.

Color-coding acts as a visual filter, drastically reducing the time it takes for users to scan their inbox and prioritize their responses.
