bump Sequencer to tendermint 0.40

[SuperFluffy]

We want to update Sequencer to use tendermint 0.40.x and all Astria's co-dependencies with it (for a complete list see below). Axum underwent heavy refactoring in its 0.7.x release. Because tonic is a core dependency of all of our services, and because tonic leans heavily on axum, updating tendermint will potentially trigger a lot of breakage in our ecosystem that needs fixing.

This update is further dependent on penumbra's 0.82.x branch, which is undergoing similar updates. This effort can is found in these pull requests:

penumbra-zone/penumbra#4963
penumbra-zone/penumbra#4973
penumbra-zone/penumbra#4980
