Subject: [PATCH] refactor: align jammy agent settings to cp+assets approach

Replace heredoc-based apply.sh scripts with static assets/agent.json
files (the same approach already used on ubuntu-noble). This makes the
two branches structurally identical so future jammy=>noble merge
forwards cannot silently resolve apply.sh conflicts in favour of the
wrong version.

- Delete prelude_agent.bash (PartitionerType: parted is now inlined as
  a static field in each assets/agent.json, as the function has
  unconditionally returned that string since 59a9c29c7 in 2019)
- Replace all 8 bosh_*_agent_settings/apply.sh heredocs with a single
  cp $assets_dir/agent.json line
- Add assets/agent.json for every stage carrying the full config
  (including UseMonitIptablesFirewall added in 8104abdd1)
