fix: add missing alt attribute to logo for accessibility

[inchara13kuppal]

Description

As part of my familiarization with the DSOMM frontend architecture for my GSoC 2026 proposal, I noticed a minor web accessibility (A11y) gap. The main logo was missing a descriptive alt attribute, which is flagged by screen readers and accessibility audits.

Changes Made

• Added a descriptive alt attribute to the <img> tag in the logo component.

Testing

• Verified UI renders correctly without regressions.
• Confirmed npm run lint passes with zero errors.

This pull request contains 10 changes that has nothing to do with the description. Not saying the changes are not good improvements. But it makes it hard to keep a tidy flow.

As for the missing alt, https://www.w3.org/WAI/tutorials/images/decision-tree/ says implies that an empty alt="" or potentially a alt="Home" would be better.

I'm sorry, I will close this request. It's fine do group similar changes in one request. But please describe them, and consider which files are included in a particular request.

Thank you for the review and the W3C link, @vbakke ! You are completely right - my branch picked up some unrelated formatting/linting changes locally that I shouldn't have pushed into this specific PR. My apologies for muddying the commit history.

I agree with the W3C standard regarding alt="" or alt="Home" for the logo. I will scrap this branch, create a clean one with only the 1-line accessibility fix, and open a fresh PR. I'll group those other UI tweaks into a separate, properly described PR later. Thanks for your patience!
