fix: native tasks missing from Tasks tab and blank title on completion

Bug 1: BuildUnifiedAtomList never called GetNativeTasks(), so doot-sourced
tasks were absent from the web Tasks tab. Added GetNativeTasks() fetch and
NativeTaskToAtom conversion (new model helper, SourceDoot constant).

Bug 2: handleAtomToggle called getAtomDetails after CompleteNativeTask, but
GetNativeTasks filters WHERE completed=0, so the task was already gone and
the title came back blank. Moved getAtomDetails call to before the completion
switch so all sources (including doot) capture title/dueDate first.

Also fixed widget_test.go compile error: TestHandleWidgetComplete_NonTodoist
called HandleWidgetComplete as a package-level function but it is a method on
*Handler. Rewrote the file as package handlers (internal) and construct
&Handler{} directly.

Regression tests added for both bugs in atoms_test.go and handlers_test.go.
