feat(approvals): live Approvals badge counts over one SSE stream

One endpoint now answers how many requests wait on every Approval Center tab, so the screen no longer makes a call per tab. - GET /v1/approvals/counts: snapshot, numbers only (held 3s, fresh=true skips). - GET /v1/approvals/counts/stream: Server-Sent Events. A `counts` event is written the moment the numbers change; one shared 1s check serves every open screen and callers counted alike share one query. Keep-alive ping every 15s, stream recycled every 5 minutes. - All 26 tabs are counted by one statement of scalar sub-selects, each the same table/status/office scope/exclusions as the tab's own API. A tab the caller may not see is not asked (permissions mirrored, disbursement for managers only). - Layered: thin API resource, ApprovalCountsReadPlatformService (+Impl), ApprovalCountsStreamService, ApprovalCounterRegistry (one line per tab). - Adds jersey-media-sse (SseEventSink / Sse).
