Swaps the unbounded vertical filter panel for a Polaris-style add-filter
builder (searchable grouped field picker, type-aware value control, applied
chips) and colour-codes the fees column with each member's period-scoped
unpaid-cycle count.
Extract the cookie parser, export-payload builder and fee-status helper
into their own modules and remove the filter/sort/load helpers the
database pushdown made dead, so the overview LiveView stays a thin
coordinator over focused units.
The View dropdown drives row density and whether the Member and Address
fields render as composite cells or split into their underlying columns;
the column manager toggles visibility and resets to the curated default.
All choices persist per browser through the URL/session/cookie/global
chain, so a saved layout survives reloads without a per-account store.
The bound-pair generator filtered out ~1/4 of generated values, so unlucky
seeds hit StreamData's FilterTooNarrowError under full property runs.
Construct an at-least-one-bound-set pair directly instead, preserving the
exact domain with no rejection.
