Enhancement: Consolidate Loader.jsx and LoadingSpinner.jsx into a single reusable component

[AA1-34-Ganesh]

Description

We currently have duplicate logic for loading spinners across the app:

1. LoadingSpinner.jsx — hardcoded size, violet color.
2. Loader.jsx — accepts size props, blue color.
3. Inline spinners inside Login.jsx.

We need to consolidate these into a single, highly reusable Loader.jsx component.

Tasks

• Update smart_exam_reval/frontend/src/components/Loader.jsx to accept props for size (small/medium/large), optional text, and fullScreen boolean.
• Delete LoadingSpinner.jsx.
• Search the codebase for imports of LoadingSpinner and replace them with the newly updated Loader component.
• Replace the hardcoded inline spinner in Login.jsx with the <Loader /> component.

Files Involved

• smart_exam_reval/frontend/src/components/Loader.jsx
• smart_exam_reval/frontend/src/components/LoadingSpinner.jsx (to delete)
• smart_exam_reval/frontend/src/pages/Login.jsx

@Samirahs08 Please wait until May 15 to request assignment or open a PR, otherwise GSSoC'26 points may not be tracked. You can still fork the repo and start exploring locally now. I will be assigning issues on a first-come, first-served basis starting on the 15th.

Hi @AA1-34-Ganesh, I'm interested in working on this for GSSOC26.
My plan is to:

1. Refactor Loader.jsx to use a switch or object mapping for sizes (small/medium/large) and add a conditional wrapper for the fullScreen prop.
2. Standardize styles to ensure the violet/blue color discrepancy is resolved (defaulting to the theme standard).
3. Global Replace: Swap all LoadingSpinner instances and the inline SVG in Login.jsx with the new unified component.

Could you please assign this to me? Thanks!
