Editable profile fields: bio, degree, year level, and links

[jenul-ferdinand]

What

Let users add and edit personal fields on their own profile. All fields public.

MVP fields:

• Bio / about me (short free text)
• Degree / course (e.g. Bachelor of Computer Science)
• Year level or expected graduation year
• Social / contact links (GitHub, LinkedIn, Discord, personal site)

Why

• A profile today is only an avatar and a username. The panel shows a "More personalisation stuff coming here soon!" placeholder, and there is commented-out bio and degree markup that was never wired up: profile-panel.component.html
• A few fields give each reviewer an identity and a reason to visit their profile.

Keep the authcate visible

• Username defaults to the email prefix and can be changed. The authcate is that prefix from a Monash student email (e.g. jfer0043 from jfer0043@student.monash.edu).
• Show the authcate on the profile even after a user renames their username.
• Reason: an always-visible authcate ties reviews to a real person and discourages bad posts. The changed username alone hides who wrote what.

Scope

• Add the fields to the user schema, the API, and an edit form on the own-profile view.
• All fields public to everyone at /user/:username.

Touch points:

• Backend schema: user.model.ts
• Frontend schema: user.schema.ts
• Profile UI: profile-panel.component.html

Out of scope

• Banner / cover images
• Accent colours or profile themes
• Per-field public/private toggles
