feat(scheduler-sim-diagnostics): display configured limit setting via fmt_limit()

repl_info_limit() now prints a matched limit's configured setting on both the
all and named-lookup success paths: fmt_limit() (existing libxce formatter,
unmodified) into a stack buffer, re-split and printed through a new
repl_print_limit_dump() helper matching this file's existing [sim]-prefix-
per-line convention. Inclusion and exclusion group membership both render
since fmt_group() already handles both, adopted as-is per design.md's
explicit reuse decision.

+- [x] 2.2 Display configured setting including scope membership
   - Matched limit's name, constrained resource, value/percent, and per-dimension scope print via the existing `fmt_limit()` library formatter into a stack buffer, line-prefixed with the existing `[sim] ` convention; all output via `fprintf(stdout, ...)`, never bare `printf()` (`test_no_bare_printf.c` regression-gates this)
   - Inclusion and exclusion group membership both render (`fmt_group()` already handles this, adopted as-is)
   - Observable: a limit configured with an exclusion group ("all except X") shows both the inclusion and the exclusion in its output; `info limit all` against a fixture with multiple configured limits displays every one's setting
