feat: Assignment service (v2) (#12320)
## Linear Link

 
## Description

This PR introduces a new robust auto-assignment system for conversations
in Chatwoot. The system replaces the existing round-robin assignment
with a more sophisticated service-based architecture that supports
multiple assignment strategies, rate limiting, and Enterprise features
like capacity-based assignment and balanced distribution.

## Type of change

- [ ] New feature (non-breaking change which adds functionality)

## How Has This Been Tested?

- Unit test cases
- Test conversations getting assigned on status change to open
- Test the job directly via rails console

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Adds a new service-based auto-assignment system with scheduled jobs,
rate limiting, enterprise capacity/balanced selection, and wiring via
inbox/handler; includes Redis helpers and comprehensive tests.
> 
> - **Auto-assignment v2 (core services)**:
> - Add `AutoAssignment::AssignmentService` with bulk assignment,
configurable conversation priority, RR selection, and per-agent rate
limiting via `AutoAssignment::RateLimiter`.
>   - Add `AutoAssignment::RoundRobinSelector` for agent selection.
> - **Jobs & scheduling**:
> - Add `AutoAssignment::AssignmentJob` (per-inbox bulk assign;
env-based limit) and `AutoAssignment::PeriodicAssignmentJob` (batch over
accounts/inboxes).
> - Schedule periodic run in `config/schedule.yml`
(`periodic_assignment_job`).
> - **Model/concerns wiring**:
> - Include `InboxAgentAvailability` in `Inbox`; add
`Inbox#auto_assignment_v2_enabled?`.
> - Update `AutoAssignmentHandler` to trigger v2 job when
`auto_assignment_v2_enabled?`, else fallback to legacy.
> - **Enterprise extensions**:
> - Add `Enterprise::InboxAgentAvailability` (capacity-aware filtering)
and `Enterprise::Concerns::Inbox` association `inbox_capacity_limits`.
> - Extend service via `Enterprise::AutoAssignment::AssignmentService`
(policy-driven config, capacity filtering, exclusion rules) and add
selectors/services: `BalancedSelector`, `CapacityService`.
> - **Infrastructure**:
> - Enhance `Redis::Alfred` with `expire`, key scan/count, and extended
ZSET helpers (`zadd`, `zcount`, `zcard`, `zrangebyscore`).
> - **Tests**:
> - Add specs for jobs, core service, rate limiter, RR selector, and
enterprise features (capacity, balanced selection, exclusions).
