fix: pad auto-generated username/name to minimum 3 characters

[Copilot]

buildAuthUserPayload derives name and username from the email prefix when those fields are required but absent — e.g. a@b.com → "a", which undercuts the ≥3-char minimum enforced in updateProfile.

Changes

• Both public-api and dashboard-api userAuth.controller.js: Extract the derived value into a variable and apply padEnd(3, '0') when its length is under 3, applied consistently to both the name and username auto-generation blocks.

// Before
payload.username = payload.name || email.split('@')[0];

// After
const generatedUsername = payload.name || email.split('@')[0];
payload.username = generatedUsername.length >= 3
    ? generatedUsername
    : generatedUsername.padEnd(3, '0');

Applies the same guard to the name fallback block for consistency.

Pull request overview

This PR updates buildAuthUserPayload in both API services to ensure auto-generated name / username values derived from the email prefix meet a minimum length of 3 characters, aligning with downstream username length requirements.

Changes:

• Auto-generate name from username or email prefix, padding to 3 chars when needed.
• Auto-generate username from payload.name or email prefix, padding to 3 chars when needed.
• Apply the same logic in both public-api and dashboard-api controller implementations.
