When creating or editing items from a project detail tab, users now
return to that project's tab instead of the entity's own page.
Edit links pass from_project param; forms include hidden field.
Reassigning to a different project redirects to the new project.
Decisions/meetings create from project context inserts junction rows.
File uploads from project context redirect back to project files tab.

Task detail page gets a Delete button in the header bar (matching
all other entity detail pages). Task edit form gets a Delete button
below the form. Both use confirmation dialog via data-confirm.
