### Motivation #27239 ### Description Changes `MirRelationExpr::typ()` to actually do repr type inference, not SQL type. While it still returns a SQL type (to be fixed in a later PR), it's a _canonical_ SQL type, obtained by mapping repr types back up to SQL types. This draft PR is on top of #35005, which should merge first. ### Verification Currently WIP. Will with nightly that #34958 successfully avoids all panics.

Motivation
#34958 removed many possible panics; #35003 sussed out another.
Description
We should only panic when types well and truly don't match---if SQL types don't align but repr types do, there is no possibility of runtime error.
Verification
Nightly, baby! This failure got sussed out by #35003, which pushes repr types into many new locations---it is likely not a reachable failure in the existing code.
