fix(clippy): inherit workspace lints in all crates

[echobt]

Summary

Ensures all workspace members inherit the workspace-level Clippy lint configuration.

Changes

• Added [lints] workspace = true to all workspace member Cargo.toml files that didn't have it
• For cortex-tui-core which has custom lint overrides, added the workspace lint allows directly since Cargo doesn't support inheriting and overriding at the same time

Why

PR #555 added workspace-level lint configuration but the crates weren't configured to inherit it. This PR ensures all crates properly inherit the unnecessary_sort_by = "allow" and iter_without_into_iter = "allow" lints.
