BSC 1.3.5 + Tuning Flags + Force Scanner Forward

The tuning flags added here appear to improve performance some, but it was insufficient to sustain line rate on the large blocks. Forcing the scanner height forward should allow nodes to reach tip quickly and hopefully sustain scan rate. Spot checked the router contract (0xb30ec53f98ff5947ede720d32ac2da7e52a5f56b) and the following vault addresses (request double check in review):

None appear to have transactions after the current consensus height (34132009) except for the following which will be skipped by forcing forward:
