Add validation to ProxyURLFromSecret to ensure proxy URLs use supported schemes (http, https, socks5) and do not exceed the maximum length of 2048 characters. This addresses the regression introduced in PR fluxcd#1041 which removed all validation after users reported SOCKS5 proxy breakage. The new implementation properly supports SOCKS5 while maintaining security through scheme and length validation. Signed-off-by: cappyzawa <cappyzawa@gmail.com>
