Trim whitespace in sanitizePath function

[SjxSubham]

Add whitespace trimming to sanitizePath function.

When a playlist name has a trailing space. this sanitizePath function only replaces invalid characters but doesn't trim leading space.

Issue
This creates a folder path like C:\Users\.. .\daniel caesar, etc. \ (with a trailing space before the backslash). Windows automatically removes trailing spaces from folder names, so the folder is actually created as daniel caesar, etc.\ but the application tries to write to the path with the space, causing the "path not found" error.
