Implement records mode (long-format view) when drilling into aggregated cells.
Key changes:
- DrillIntoCell now creates views with _Index on Row and _Dim on Column
- GridLayout detects records mode and builds a records list instead of
cross-product row/col items
- Added records_display() to render individual cell values in records mode
- GridWidget and CSV export updated to handle records mode rendering
- category_names() now includes virtual categories (_Index, _Dim)
- Tests updated to reflect virtual categories counting toward limits

Add view navigation history with back/forward stacks (bound to < and >).
Introduce CategoryKind enum to distinguish regular categories from
virtual ones (_Index, _Dim) that are synthesized at query time.
Add DrillIntoCell command that creates a drill view showing raw data
for an aggregated cell, expanding categories on Axis::None into Row
and Column axes while filtering by the cell's fixed coordinates.
Virtual categories default to Axis::None and are automatically added
to all views when the model is initialized.

Refactor DataStore to use interned keys (InternedKey) instead of
string-based CellKey for O(1) hash and compare operations.
Introduce SymbolTable-backed interning for all category and item
names, storing them as Symbol identifiers throughout the data structure.
Add secondary index mapping (category, item) pairs to sets of interned
keys, enabling efficient partial match queries without scanning all cells.
Optimize matching_values() to avoid allocating CellKey strings by
working directly with interned keys and intersecting index sets.
Update all callers to use new API: iter_cells(), matching_values(),
and internal lookup_key() helper.

Extend FieldProposal with chrono-based date format detection and
configurable component extraction (Year, Month, Quarter). Add
ConfigureDates and DefineFormulas wizard steps to ImportPipeline.
build_model injects derived date categories and parses formula strings.

Categories on the None axis are excluded from the grid and cell keys.
When evaluating cells, values across hidden dimensions are aggregated
using a per-measure function (default SUM). Adds evaluate_aggregated
to Model, none_cats to GridLayout, and 'n' shortcut in TileSelect.
