style(tui): apply rustfmt and clippy formatting across crate

Mechanical formatting pass to satisfy rustfmt line-width limits and
clippy pedantic/nursery lints. No behavioral changes.

Formatting (rustfmt line wrapping):
- action/sync.rs: multiline tuple destructure, function call args in tests
- state/sync.rs: if-let chain formatting, remove unnecessary Vec collect
- view/sync.rs: multiline array entries, format!(), vec! literals
- view/doctor.rs: multiline floor_char_boundary chain
- view/scope_picker.rs: multiline format!() with floor_char_boundary
- view/stats.rs: multiline render_stat_row call
- view/mod.rs: multiline assert!() in test
- app/update.rs: multiline enum variant destructure
- entity_cache.rs: multiline assert_eq!() with messages
- render_cache.rs: multiline retain() closure
- session.rs: multiline serde_json/File::create/parent() chains

Clippy:
- action/sync.rs: #[allow(clippy::too_many_arguments)] on test helper

Import/module ordering (alphabetical):
- state/mod.rs: move scope_picker mod + pub use to sorted position
- view/mod.rs: move scope_picker, stats, sync mod + use to sorted position
- view/scope_picker.rs: sort use imports (ScopeContext before ScopePickerState)
