fix(screener): align filter labels and row hover

[kirillDevPro]

Summary

• derive the Market and Vol. footer labels from the Screener column schema
• consume MoonUI's stronger semantic table hover from upstream PR feat(core-selectors): toggle exchange groups #58
• pin Cargo.lock to merged MoonUI commit 3a005c15
• add regression coverage for footer/header label synchronization

Validation

• cargo test --workspace
• cargo clippy --workspace --all-targets
• mutation proof: green -> Coin/DVol literals -> red -> restore -> green
• MoonUI guardrails passed upstream
• final Windows executable shipped before publication

MoonUI dependency: Moonbot-Tech/MoonUI#58
