Allow users to manage their profile photo [PlanID: 2023.3/27/1.5]

[darh]

Administrators can enable (default) or disable if users can set their own profile photo in the auth/profile pages. The profile photo is either an uploaded photo or custom initials (1-3 ASCII characters) with a custom background and text colour. Administrators can also upload and set the initials with colours for any user via the admin panel.

The profile photo is then used on the top navigation on the right side.

---

• for image - we accept JPEG and PNG formats, max size (propose)MB, resize to (propose)x(propose)px dimensions.
• admin can enable/disable photo upload (enabled by default)
• admin can enable/disable "the initials" feature (enabled by default)
• create a special endpoint to serve profile photos for users, accepts user-id and dimensions (resized on-demand)
• in-browser resizing and cropping is a bonus.

Additional functionality has been added to the avatarInitials image generation when creating a new user:

1. If the user's first name is available, the initials will be the first two letters of the name (e.g., John => JO).
2. If the user's full name is available, the initials will be the first character of the first and last names (e.g., John Doe => JD).
3. If the user has three or more names, the first three characters of the first, second, and third names are taken to form the initials (e.g., John Doe Test => JDT, John Doe User Test => JDU).
4. If the user's handle exists and their name doesn't, the initials will be the first letter of the handle (e.g., john => J). If the handle contains delimiters such as ., _, or -, the handle name is split using those delimiters, and the first letter from the first and second parts is used as the initials (e.g., john.doe => JD, john-doe.me => JD, john_doe.me-you => JD).
5. If both the name and handle don't exist, the initials will be the first letter of the email (e.g., john.doe@tld.dev => J). If the email name contains delimiters before the @ symbol, the email name is split using those delimiters, and the first letter from the first and second parts is used as the initials (e.g., john.doe@tld.dev => JD, john-doe.me@tld.dev => JD, john_doe.me-you@tld.dev => JD).
