[fix](fe) Fix NoSuchElementException when count with MATCH_ALL expression

Issue Number: close #???

Problem Summary:
When executing explain on SQL like:
  SELECT count(col MATCH_ALL 'xxx') FROM table WHERE ...
The Nereids optimizer throws NoSuchElementException because storageLayerAggregate
rule tries to get originalColumn from a SlotReference that represents a virtual
column (generated from MATCH_ALL expression). The virtual column has no physical
column in the table schema, so getOriginalColumn() returns Optional.empty().

The fix adds proper isPresent() checks before calling get() on Optional.

Release note:
Fix a bug where count(MATCH_ALL) causes explain to fail with NoSuchElementException

Test:
- Added regression test test_count_match_all_pushdown to cover this case
