fix: load survey script directly via src instead of blob URL

Fixes FORMBRICKS-TQ The blob URL approach was being blocked by CSP which doesn't include 'blob:' in script-src directive. Simplified to load script directly via src attribute: - Works with existing CSP ('self' is allowed) - No need for fetch, blob URLs, or eval - Properly executes and initializes window.formbricksSurveys - Adds cache-busting in development for fresh script loads
chore: remove test files

Cursor Agent	75e47b4979	fix: use blob URL to execute survey script and initialize window.formbricksSurveys Fixes FORMBRICKS-TQ The script content was being assigned to textContent which may not execute properly in all contexts. Changed to use a Blob URL approach which: - Creates a blob from the fetched script content - Loads it via script src attribute (works with CSP without unsafe-eval) - Properly waits for script execution before proceeding - Ensures window.formbricksSurveys is initialized correctly - Cleans up the blob URL after loading to prevent memory leaks	2026-03-18 12:31:17 +00:00
Cursor Agent	7504c47fc1	fix: execute survey script in global scope to initialize window.formbricksSurveys Fixes FORMBRICKS-TQ The script content was being assigned to textContent instead of being executed, preventing the window.formbricksSurveys object from being initialized. Changed to use indirect eval pattern to execute the script content in the global scope, ensuring proper initialization.	2026-03-18 12:22:53 +00:00
