test: remove per-test deadlines owned by project policy

Explicit deadlines at or below the project deadline only shortened it:
a literal 30-second value also disabled the coverage scaling, which timed
out wide-capacity regressions on main. Workloads above the built
deadline use the long-running tag. Deadlines derived from an operation
budget remain.
