Add Dataview and Bases generators (Toolbox Phase 2)

Two more inside-LMS generators under /tools, completing the 6-tool set:
- Dataview: DQL builder (TABLE/LIST/TASK/CALENDAR, FROM/WHERE/SORT/LIMIT),
  output wrapped in a dataview code block
- Bases: .base YAML builder (views, filters and:, order, sort, groupBy, limit);
  filter expressions emitted as single-quoted YAML scalars for safety

Syntax verified against official Obsidian docs (research workflow). Audit fix:
Bases sort entries use 'column:' (not 'property:') per documented working .base
files; 'property:' is kept only for groupBy. 14 new tests (47 total).
