Root cause: single global 'cur' node ID was shared across all
sections. Switching between 'Клиенты'/'Проекты'/etc did not
change the rendered content because renderToday/renderInbox/
loadSection all loaded the same flat root-node list and
switchTab('ov') re-rendered selN(cur) regardless of which
section was active.
Fix: split selection into two distinct states:
sel = {kind:'section', section:'today'|'inbox'|'clients'|...}
or sel = {kind:'node', nodeId:'<uuid>'}
Each section renders its own content (title, quick-actions,
filtered items, empty state). Real nodes show their own
dashboard. Tab dispatch checks sel.kind first.
Sidebar separated into:
'НАВИГАЦИЯ' — virtual sections (today/inbox/7 categories)
'ДЕЛА' — real user nodes from API
Russian type labels everywhere (TL map). Section metadata
(SEC_META) provides per-section empty states and action types.
Known limitation: section content currently shows all root
nodes (backend has no section/group column yet). When section
assignment is added to the data model, filtering will wire
up without frontend changes — renderSectionList already
receives the section id.
