@Ritikavarshney-hub what you've done is really great, but the texts in the light mode become invisible due to their light colours. Please fix that. |

Which issue does this PR close?
Rationale for this change
Currently, Spamlyser has a fixed dark theme, which may not be preferred by all users. Adding a theme toggle improves accessibility, user comfort, and visual customization without impacting core functionality.
What changes are included in this PR?
Added a Dark/Light theme toggle in the sidebar
Made theme preference persistent using st.session_state
Applied automatic theme-based styling to all Plotly charts
Added smooth fade transition for theme switching
Are these changes tested?
Yes — tested locally with:
Single message classification
Batch CSV upload and analysis
Switching between all models
Both light and dark modes
Are there any user-facing changes?
Yes — a theme toggle appears in the sidebar, allowing users to switch between dark and light mode instantly.
