Fix CI test failures: rename AccountConstraints structs, fix clippy, add Quasar pyth files

- Remove AccountConstraints suffix from all Anchor account struct names so
  tests referencing the shorter names (e.g. CreateToken, InitRentVault) compile
- Fix Clippy warnings in lever/src/lib.rs: prefix unused context with _,
  remove unnecessary mut on switch_power context parameter
- Create missing oracles/pyth/quasar/src/instructions/read_price.rs and
  src/tests.rs so the Quasar pyth build and test steps succeed
