YQ AltLayer eabbd68c19 triedb/pathdb: fix trienode history gap when newly enabled on existing node 
When enabling trienode history (--history.trienode=0) on a node that
already has state at block N, repairHistory() returns a fatal error:
"gap between state [#N] and trienode history [#0]"

This happens because the newly created trienode freezer has 0 entries
while state is at block N. The gap check on line 427 treats this as a
data corruption error, but the function's own comments document that
it should "detect and resolve such gaps" for the optional trienode
history.

Fix by detecting the newly-enabled case (empty freezer + non-zero
stateID) and skipping both the gap check and the head truncation.
An empty freezer with head=0 would also fail truncateFromHead because
ohead(0) < nhead(stateID) is outside the valid range.

The trienode history will begin accumulating naturally from the
current state forward, which is the expected behavior documented
in the v1.17.0 release notes.

Fixes ethereum/go-ethereum#33907
