Reuse Shared Bootstrap Schema Loader in CLI

[findolor]

Background

storage.rs under the CLI commands initializes sqlite schema and bootstrap data separately from the WASM path. Planned improvements to the shared sync module include configurable bootstrap/dump loading.

Problem

Keeping a CLI-specific schema initializer introduces drift and doubles the work when bootstrap behavior changes.

Proposed Approach

1. After the shared sync module exposes a configurable bootstrap loader, wire the CLI storage code to use it instead of maintaining its own copy.
2. Remove redundant initialization logic from storage.rs, keeping only CLI-specific filesystem handling.
3. Verify that CLI bootstrap behavior matches the shared path through integration tests.
