fix(proxy): CancelKeyData display log masking

[conradludgate]

Fixes the masking for the CancelKeyData display format. Due to negative i32 cast to u64, the top-bits all had 0xffffffff prefix. On the bitwise-or that followed, these took priority.

This PR also compresses 3 logs during sql-over-http into 1 log with durations as label fields, as prior discussed.
