subdict_match only applied regex/fnmatch patterns to list members and to literal dict keys, so a pattern like 'roles:(roleA|roleB|roleC)' matched a list-valued grain but not the equivalent dict-valued grain. Scan dict keys with the same _match() helper used for list members so key matching is consistent. Fixes saltstack#35567
The PR's existing test already exercises subdict_match directly with regex_match=True (the exact flag grain_pcre_match passes) and the plain glob shape grain_match passes. This adds the inverse guard: the new key-matching branch runs for every caller, so exact_match=True (the shape pillar_exact_match and the minions cache check pass) must keep glob/regex metacharacters literal, a non-matching glob must not match, and a key-only match must not satisfy a deeper expression whose lower levels do not match. All inverse assertions hold with and without the fix applied.

What does this PR do?
subdict_match in salt/utils/data.py only applied regex/fnmatch to list members and to literal dict keys, so a PCRE/glob pattern like 'roles:(roleA|roleB|roleC)' matched a list-valued grain but returned False for the equivalent dict-valued grain (issue #35567, reproduced against 3006.x). The fix adds a key scan in _dict_match using the existing _match() helper so dict keys are matched consistently with list members. Verified the new unit test fails on unpatched code (stashed the source fix -> FAIL) and passes with the fix; existing subdict_match tests still pass. Note: pytest hangs unless the pytest-salt-factories plugins are disabled via -p no:..., which is why the test command lists them.
What issues does this PR fix or reference?
Fixes #35567
Previous Behavior
See #35567.
New Behavior
Fix grain PCRE/glob matching against dict-valued grains. Validated by a unit test proven to fail on unpatched 3006.x and pass with the fix (confirmed by adversarial review).
