Add PM extension (Projects, Work Logs, Comments) + Quill rich-text UI

Projects: Brick-backed model with list/detail screens and nav entry.
Work Logs: per-contributor time ledger, assignee running-clock +
helper logged minutes with Hours/Minutes input; pause-after-save and
helper-deduct prompts.
Comments: threaded comments with file attachments and Quill composer.
Detail screen: tabbed layout (Work Log / Comments / Activity),
editable title + description via edit dialog, Quill-rendered
descriptions with legacy plain-text fallback.
Create dialog: fixed-width (480px max), Quill description editor.
Shared QuillFieldEditor + QuillReadOnly widgets extracted for reuse.
RLS: hardened activity-log actor binding, immutable creator_id/
created_at triggers, SECURITY INVOKER visibility helper,
append-only work-log and scoped comment policies.
Brick migration for project_id FK on programmer_tasks.
