Teknium 771045655b refactor(agent/models): table-driven credits header parsing, unified account-usage fetchers
- credits_tracker: _MICROS_FIELDS/_USD_FIELDS/_BOOL_FIELDS drive parse_credits_headers;
  _sticky_notice() replaces repeated AgentNotice literals; collapsed defensive layers
- account_usage: _USAGE_FETCHERS dispatch table replaces provider if/elif; shared
  fetch/parse helpers across the codex/anthropic/openrouter fetchers; drop dead
  _resolve_codex_usage_url
- billing_links, fast_mode: compacted docstrings, collapsed if/return chains
- model_metadata: fold effective_provider inference into one expression
Notice keys, header names, URLs, log strings and dataclass defaults unchanged.
