Guillem Arias 45c61bcbc1 feat(ai): add Anthropic batch ops + LLM cost ledger (2/5)
Implements auto_categorize, auto_detect_merchants, and
enhance_provider_merchants on Provider::Anthropic via forced tool calls,
plus the cost-ledger plumbing they need.

- Provider::Anthropic::AutoCategorizer, AutoMerchantDetector,
  ProviderMerchantEnhancer each define a single output tool whose
  input_schema mirrors the desired output, then force the model to call
  it via tool_choice: { type: "tool", name: ..., disable_parallel_tool_use: true }.
  Anthropic guarantees the tool_use.input matches the schema, so there
  is no JSON parsing fragility, no <think> tag stripping, and no
  json_object/json_schema fallback ladders.
- Concerns::UsageRecorder mirrors the OpenAI sibling but persists
  cache_creation_input_tokens / cache_read_input_tokens to dedicated
  columns instead of metadata.
- Migration adds cache_creation_tokens, cache_read_tokens (nullable
  integers) to llm_usages. OpenAI rows leave them null.
- LlmUsage::PRICING gains Claude 4.x rows (opus-4-7 $15/$75, sonnet-4-6
  $3/$15, haiku-4-5 $1/$5 per MTok). infer_provider returns "anthropic"
  for claude-* via the existing exact/prefix lookup.
- Provider::Anthropic#chat_response now persists cache columns directly
  rather than stashing them in metadata.
- 25-transaction batch cap mirrors the OpenAI provider so the cost
  ledger sees the same shape regardless of which provider ran a batch.

Tests cover the forced-tool-call path, null/None normalization,
case-insensitive merchant matching, the missing-tool_use error path,
and Anthropic-specific pricing + provider inference on LlmUsage.

Stacked on #1983 (PR 1/5). 3/5 PDF + vision next.
