feat: resource view registries for ledger tables and panels

[roncodes]

Extensions can add columns, row actions, bulk actions and toolbar buttons to ledger tables through ledger:table:<resource>:<slot>. They can add header buttons and "…" menu items to ledger's details panels through ledger:details:<resource>:<slot>.

Resources: account, gateway, invoice, invoice-template, journal, transaction, wallet.

Changes

• @registry on every Layout::Resource::Tabular index view and every Layout::Resource::Panel details view.
• Gateway::Hub renders its own column picker, so the gateways controller merges registered columns once via gatewayActions.mergeRegisteredColumns. The registry goes to the hub's TabularActions for buttons and bulk actions.
• Stable ids on built-in columns, actions and buttons (a column's dasherized valuePath, an action's handler name), so registered items can anchor with before/after.
• Index queryParams go through <x>Actions.queryParamsFor(), so registered filter columns work.
• Registries declared in extension.js.

Depends on

• feat: resource view registries for table and details views ember-core#95 (release 0.3.25)
• feat: render resource view registries in tables and panels ember-ui#186 (release 0.4.5)

Merge only after both are published. Before merging, bump @fleetbase/ember-core to ^0.3.25 and @fleetbase/ember-ui to ^0.4.5, and refresh the lockfile. Until then this branch builds against the old APIs and will not run.

Naming and API reference: docs/resource-view-registries.md in ember-core.

Testing

Lint and template-lint pass. No tests were run locally.
