apollo_deployments: delete base app_configs and the preset-parity test machinery

[nimrod-starkware]

jsonnet build() is the sole source of the node config, so the committed base
app_configs/config.json and the build()-vs-app_configs parity test are dead.
Delete the 21 base *config.json, merged_app_configs/non_default_paths/
test_applicative_matches_app_configs and the applicative_matches_app_configs test,
plus their last-user constants KEYS_TO_BE_REPLACED and BASE_APP_CONFIGS_DIR_PATH
(and the now-dead get_component_config{names,file_paths}), and drop the freed phf
dep. Keep CONFIG_POINTERS/dump()/config_to_preset definitions and the
build_deserializes + *_infra_matches_rust guards (later phases own those).

apollo_deployments 8/8 green; cdk8s synth 31/31 green (build() sole source).

PR Summary

Medium Risk
Large deletion of committed default config snapshots and their guard test; runtime defaults now depend entirely on jsonnet build() unless replacers cover gaps.

Overview
Removes the committed base resources/app_configs/*_config.json snapshots (21 files) now that jsonnet build() is the sole applicative config source.

Strips the machinery that kept those files in sync: test_applicative_matches_app_configs, applicative_matches_app_configs, merged_app_configs / non_default_paths, KEYS_TO_BE_REPLACED, BASE_APP_CONFIGS_DIR_PATH, ComponentConfigInService::get_component_config_*, and is_path_prefix in test utils. Drops the unused phf dependency and AsRefStr on ComponentConfigInService.

Unchanged: jsonnet replacer_* app_configs (still referenced by deployment replacer manifests), plus build_*_deserializes and *_infra_matches_rust parity tests.
