fix: add suspended state to oban_job_state enum (#199)

Oban 2.18+ introduced the 'suspended' job state for pausing jobs.
Oban.Met.Reporter queries for jobs in this state, causing errors when
the database enum doesn't include it:

  ERROR 22P02 (invalid_text_representation) invalid input value
  for enum oban_job_state: "suspended"

This migration adds 'suspended' to the oban_job_state enum type.

Required by recent Oban dependency updates (commit 0399b30d).

Note: Uses @disable_ddl_transaction since ALTER TYPE ADD VALUE cannot
run inside a transaction in PostgreSQL.
