Implement character, currency, and shop changes

[konard]

Fixes #7

Summary

• Added character fields for ability scores, subclass, race, investigation, HP, armor class, and background.
• Extended inventories with gold, silver, and copper plus item rarity and consumable flags.
• Wired inventory/shop routes into the FastAPI app and added rarity-based shop search, buy, and sell flows with character or hireling modifiers.
• Moved table creation into FastAPI lifespan startup so tests can override the database cleanly.

Reproduction and Verification

• Reproducing coverage: tests/test_issue_7.py exercises the new character fields, split currency normalization, item rarity/consumable storage, successful buy, failed search cost behavior, and selling only owned items.
• Local checks: pytest -q passed with 5 tests.

API Notes

• Buy/search requests accept rarity, is_consumable, searcher_type, and hireling_level.
• Sell requests require an owned item_id; successful sales remove the item and add calculated currency.
