feat(server): add Exposed ORM database layer with H2
...
server/db/Tables.kt:
- Exposed table definitions for Categories, Locations, Items, Settings
- Schema mirrors Room entities from app module
- Foreign keys on Items referencing Categories and Locations
server/db/DatabaseFactory.kt:
- H2 file-based DB initialization (jdbc:h2:file:./data/krisenvorrat)
- Parameterized for testability (in-memory DB for tests)
- Schema auto-creation via SchemaUtils.create()
server/repository/InventoryRepository.kt:
- Full CRUD: saveInventory() and loadInventory()
- Atomic replace via transaction (deleteAll + insert)
- Direct mapping between Exposed rows and shared DTOs
4 repository tests with H2 in-memory covering:
- Empty DB, full round-trip, overwrite, nullable fields
Closes #41
