Fix algorithm selection not persisting from URL query parameters

[SamMed05]

I just noticed a bug introduced with the URL params saving feature: when opening a shared URL with algo and processes parameters (e.g., ?algo=SRTF&processes=[...]), the algorithm parameter was being dropped from the URL and the algorithm dropdown remained unselected.

It appears that the URL update effect rebuilt search params from scratch before the form initialized with URL values, causing the algo parameter to be dropped during React hydration. It weirdly wasn't happening when I tested locally, but it's now fixed.

Fix

• Initialize form with defaultValues that read from URL params synchronously
• Start URL updates from existing window.location.search instead of empty URLSearchParams
• Add proper guards and dependency arrays to prevent race conditions
• Sync selectedAlgorithm state with form value via dedicated effect

It should all work properly now. Take your time to review this, and let me know if you notice any issues.
Thanks for your patience with all the PRs, this should be the last one 😅

Thank you for noticing this issue. I am sure i would not have caught this any time soon XD.

I have tested it out and it works as expected. I will be merging this.

Thank you for your time and efforts towards this project! I might do a bit of a UI update later on where i will add your name as a contributor on the website. Might not be much but this is all i can do for now XD.

It was a pleasure looking at your code and how you tackled issues. Keep up the good work!
