apollo_deployments: retire dead preset/replacer generation machinery

[nimrod-starkware]

Runtime (Phase 1) and the cdk8s deploy (Phase 2) now load only native config, so
the preset-replacer GENERATION machinery is dead. Remove it:

• Delete resources/app_configs/replacer_*.json (19 files), src/replacers.rs, and the
  deployment_generator bin (+ its [[bin]] entry and the tempfile dev-dep).
• service.rs: drop the replacer-annotation plumbing, the deploy-path config_to_preset/
  prune_by_is_none calls, and the orphaned ComponentConfigsSerializationWrapper. Keep
  KEYS_TO_BE_REPLACED (still feeds the retained applicative_matches_app_configs guard's
  exclusion set).
• Delete the 3 migration guard tests (deployment_files_are_up_to_date,
  replacer_config_entries_are_in_config, duplicate_config_entries). Keep the
  build_*_deserializes, applicative_matches_app_configs, and *_infra_matches_rust guards,
  and get_component_configs.

The cdk8s configList field is presence-checked only (its targets live in a different
directory and are not read under native), so deleting the base replacer JSONs leaves
synth green. apollo_deployments: 9 tests pass; cdk8s synth green for all overlays.

PR Summary

Low Risk
Deletion of unused generation code and committed JSON artifacts; retained tests still guard jsonnet vs app_configs and infra parity.

Overview
Removes dead deployment preset/replacer generation now that runtime and cdk8s deploy load native config only.

Deletes the deployment_generator binary, replacers.rs, all 19 replacer_*.json app config templates, and the [[bin]] / tempfile dev-dependency wiring. service.rs no longer dumps replacer-annotated configs (config_to_preset, prune_by_is_none, ComponentConfigsSerializationWrapper, replace_pred, and per-service replacer file paths); KEYS_TO_BE_REPLACED stays as the exclusion set for applicative_matches_app_configs.

deployment_definitions drops replacer path helpers and CONFIG_BASE_DIR. Three migration tests (deployment_files_are_up_to_date, replacer_config_entries_are_in_config, duplicate_config_entries) are removed; jsonnet/Rust parity and build-deserialize guards remain.
