bug-1962: apiserver JWT excluded-path check drops the last character of every entry, matching unintended paths

Description

Observed: (source reading; follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)) ValidateHandler.isExcludedPath (middleware/validatehandler.go:52-61) trims the last character of every excluded entry, not only a trailing *, and matches by prefix: /ping matches any path starting with /pin, and /swagger/*any never matches.

Expected: Exact entries match exactly; only entries ending in * match by prefix. Impact: Security: paths that merely share a prefix with an excluded entry skip JWT validation. Found by: follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)

Environment

• OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
• libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
• Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
• Build: asan (xce.build)
• Code: scheduler-framework @ 19be145d-dirty
• Deployment: any (found by source reading; confirmed by the RED test of the fix)

Reproduction

1. Request /pinX (or any route sharing the prefix) without a token: JWT validation is skipped.

• Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
• Evidence: the code sites quoted in Description; no logs kept.
