refactor: split MapLive.Index into focused modules
Some checks failed

Some checks failed
Build and Push / Build and Push Docker Image (push) Failing after 2s
- State (177 lines): mount assigns, defaults, slideover, connection status - Events (540 lines): 22 handle_event handlers, rate limiting, URL helpers - Subscriptions (122 lines): PubSub setup, spatial registration, cleanup - BoundsUpdater (172 lines): bounds pipeline, validation, debouncing - index.ex: 2,062 -> 1,202 lines (42% reduction) - Credo: initial_historical_completed, bounds_update_timer added to ignored_assigns (consumed by extracted modules, invisible to credo) - All 361 map_live tests pass across multiple random seeds - Handoff: marked maintainability #1 as done

## Remaining maintainability work
|
||||
|
||||
1. Split `AprsmeWeb.MapLive.Index` into focused state, event, subscription, and
|
||||
rendering modules. Preserve LiveView behavior with integration tests first. **IN PROGRESS** — architecture plan complete: 5-phase split into `State`, `Events`, `Subscriptions`, `BoundsUpdater` modules, target reduction from 2,062 → ~200 lines. Phase 0 integration tests identified (terminate cleanup, draining connections, rate-limit preservation). Ready to implement.
|
||||
1. ~~Split `AprsmeWeb.MapLive.Index` into focused state, event, subscription, and
|
||||
rendering modules. Preserve LiveView behavior with integration tests first.~~ **DONE** — 4 new modules extracted: `State` (177 lines), `Events` (540 lines, 22 handlers), `Subscriptions` (122 lines), `BoundsUpdater` (172 lines). `index.ex` reduced from 2,062 → 1,202 lines (42% reduction). All 361 tests pass across multiple seeds. Rendering (locate_button, bottom_controls) intentionally kept in index.ex as template code.
|
||||
2. ~~Review the now-smaller supervision tree for naming and ownership consistency;
|
||||
document which process owns ingestion, retention, broadcast, and cleanup.~~ **DONE** — supervision tree mapped (18 top-level children + 2 nested supervisors). Ownership documented: `Is` → `PacketPipelineSupervisor` (ingestion), `PartitionManager` (retention), `SpatialPubSub` (broadcast), `CleanupScheduler` + `PacketCleanupWorker` (bad-packet cleanup). Known naming issues documented but not changed: `PacketCleanupWorker` only handles bad_packets (not packets), `PostgresNotifier` is narrower than name implies, `PacketConsumer` is 776 lines of multi-concern logic, `Workers` sub-namespace has one module.
|
||||
3. ~~Continue deleting obsolete configuration keys, telemetry names, docs, mocks,
