Closes the two cross-cutting filter gaps in launch-readiness (rep
multi-select + source multi-select). The Sales detail tables can now be
narrowed by assigned rep and lead source alongside the existing stage /
lead-category / outcome filters.
- service: thread `assignedTo` + `sources` through the 5 filtered Sales
queries (rep-performance, stalled, closing-this-month, recent-wins,
lost-reason); add `getRepFilterOptions` for the rep dropdown's stable
option list (distinct assigned reps port-wide, window-independent).
- route: extract param parsing into a pure, unit-tested
`parseSalesFilters` helper (source allowlisted against SOURCES;
assignedTo passed through as free user-id list); return `repOptions`
in the payload.
- ui: static Source filter (SOURCES) + dynamic "Assigned to" filter
(from payload repOptions, hidden until loaded); decouple the query
builder from dynamic options via a stable FILTER_KEYS list.
TDD: 8 new parseSalesFilters unit tests (allowlist drop, free-list
passthrough, combine). tsc clean; 12/12 reports unit tests; browser-
verified both filters fire `source=`/`assignedTo=` → 200.
