lpGetInteger returns int64_t, avoid overflow (#10068)

Fix #9410

Crucial for the ms and sequence deltas, but I changed all
calls, just in case (e.g. "flags")

Before this commit:
`ms_delta` and `seq_delta` could have overflown, causing `currid` to be wrong,
which in turn would cause `streamTrim` to trim the entire rax node (see new test)
