test: fix the weak assertions from the S6/S7 audit

The Hyprland socket check passed a shell glob to `test -S`, which breaks at both edges: zero matches leaves the literal pattern and several instances pass multiple args, failing for reasons unrelated to the socket. It now resolves one socket with find -type s.

The gen_tokens degenerate-marker test asserted properties loose enough to pass on garbled output. It now pins the exact reconstruction as a characterization, with the impossible-input caveat stated, so any change to the branch surfaces.

The gallery tick count leaned on split-string omit-nulls arithmetic that happened to equal the match count. It now counts occurrences directly. gallery-widget-write-svg, the last uncovered public entry point, gets a Normal-case test.
