 3e1dc3c886 fix: replace strtolower/strtoupper with locale-independent wrappers (#6717) 
* cleanup: remove unreachable defensive error logs in aggregate graph item validation

* fix: replace strtolower/strtoupper with locale-independent wrappers

PHP 8.5 deprecates locale-sensitive strtolower() and strtoupper().
Add cacti_strtolower() and cacti_strtoupper() wrappers that use
mb_strtolower/mb_strtoupper with explicit UTF-8 encoding, then
replace all 185 call sites across 65 files.

Existing mb_strtolower() calls (email normalization) are left as-is
since they already specify encoding explicitly.

Includes 18 Pest tests covering ASCII, UTF-8, protocol names, config
values, hex strings, NaN detection, and file extension patterns.

* fix: correct docblock references and month_shift() strpos check

Fix docblocks to reference strtolower()/strtoupper() (the deprecated
PHP builtins) instead of the wrapper names. Fix month_shift() to use
strpos() !== false instead of > 0 so 'month' at position 0 is matched.

Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

* chore: drop unrelated lib/api_aggregate changes

Keep PR scope focused on the issue for this branch.
