feat(supervisor): phase 7d — outbound allocation and reallocation suite (generic, grievance, everwell)

[Madhav2402]

📋 Description

• Phase 7d — the supervisor's allocation/reallocation suite for all three outbound flavors: unallocated-count search + allocate-to-agents (menu cases 12/29/26) and per-agent reallocation + move-to-bin (cases 13/30/27). The old app had three near-identical component sets; this PR ships ONE parameterized allocate-records child + one allocation parent + one reallocation parent, flavor-driven, with every backend body byte-faithful. Stacked on feat(outbound): phase 7c — outbound worklist hub, dial hand-offs and outbound call loop #10 — please review/merge feat(supervisor): phase 7b — activity console shell, telephony iframes, supervisor entry route #9 → feat(outbound): phase 7c — outbound worklist hub, dial hand-offs and outbound call loop #10 first; this PR's diff is the 2 phase-7d commits.

What's in this PR

AllocationApiService (flavor-driven, bodies byte-faithful)

• Generic: call/outboundCallCount / outboundCallList (is1097:true) / outboundAllocation {roleID, userID[], allocateNo, outboundCallRequests} / resetOutboundCall {outboundCallReqIDs}
• Grievance: unallocatedGrievanceCount, allocatedGrievanceRecordsCount, allocateGrievances/reallocateGrievances {startDate, endDate, providerServiceMapId, language, fromUserId, roleID, touserID[], allocateNo}, moveToBin {…, noOfCalls, is1097}
• Everwell: everwellCall/* with the providerServiceMapId/agentId casing, bin by {eapiIds}
• dayBoundary() reproduces the old timezone-shifted day-window strings (T00:00:00.000Z / T23:59:59.000Z / T23:59:59.999Z); localDate() parses picker values as local midnight (the old md2 pickers produced local Dates)

One shared AllocateRecordsComponent (replaces the old app's three clones)

• Role → agents (multi-select, language-filtered like the old allocation fetch; the excluded source agent filtered by name in reallocation) → even split across agents → flavor-specific allocate POST
• Flavor-faithful quirks kept: grievance resets an out-of-range allocateNo to 0 (old validate); generic clears below 1 / clamps to the pool; everwell has no upper clamp before an agent is selected (the old everwell read its count off the response envelope, leaving it undefined) but clamps to the per-agent share after selection; grievance prefills on ROLE change; generic/grievance error alerts show the bare HTTP status, everwell shows the error message (old handlers)
• The grievance allocate posts the raw picker date instants (old onCreate payload), not the count-query boundaries

Allocation parent (cases 12 / 29 / 26)

• Default window today → today+7 with the old boundary strings; date + language filters; per-language count table; Allocate per non-All row (disabled at 0)
• Post-allocation refresh refetches without the language filter (old child emitted no language)

Reallocation parent (cases 13 / 30 / 27)

• Role → agent → per-language counts; Reallocate (child with the source agent excluded) + Move to Bin (grievance bins directly with noOfCalls; generic/everwell fetch the agent's records then reset by outboundCallReqIDs/eapiIds)
• No date filters — the old pickers were display:none dead UI on every flavor and never posted
• The old reallocation agents fetch carried no language filter (asymmetric vs allocation) — kept

Declared deviations (frontend-only)

1. Deselecting all agents resets allocateNo to the full pool (the old grievance branch); the old generic/everwell divided by zero there (allocateNo = Infinity) — not replicated (the form is unsubmittable without agents either way)
2. localDate()/local default dates fix UTC/local day-shift artifacts the old local-Date pickers never had (rendering + query-window correctness for non-IST timezones; identical strings in IST)

Verification (live against UAT, 1097Supervisor)

• All six menu pages mount; count payloads byte-exact for all three flavors (incl. the default-window strings and everwell casing)
• Reallocation chain with real data: role → agents → per-language counts; All-only rows correctly hide actions
• Child with real fetches: language-filtered agents (2 of 4 matched Hindi), record-list payload in the old child's exact date format
• Flavor clamp rules re-verified in-browser post-review: grievance 500→0 / 0→0 with prefill-on-role; generic 500→20 / 0→clear; everwell 500 unclamped pre-selection
• ng build clean, tsc clean, GPL header check passing

ℹ️ Additional Information

• The Allocate / Move-to-Bin buttons were deliberately NOT exercised against UAT (they would assign or unassign real worklist records); the allocate payloads are code-verified against the old sources, and a live write test is planned with disposable test data / the mentor demo.
