fix: regression bug when multiple routes share parent paths

[paulpopus]

What & why

Fixes a regression where two custom admin views sharing a parent path could resolve incorrectly depending on the order they were registered in the views object.

For example, given:

views: {
  ordersIndex:  { path: '/orders' },
  orderDetail:  { path: '/orders/:id' },
}

Navigating to /orders/123 previously resolved to ordersIndex (the prefix match registered first) instead of the more specific orderDetail. Reversing registration order changed the result, making behavior non-deterministic from a user perspective.

The custom-view resolver used Object.entries(views).find(...), which returns the first match. This change replaces the early-exit lookup with a full scan that ranks all matching views by specificity and picks the best one.

Specificity ranking

When more than one custom view matches the current URL, the winner is chosen by:

1. Longest matched portion of the URL wins (/orders/:id → 11 chars vs /orders → 7 chars for /orders/123)
2. If equal, exact: true wins over a prefix match
3. If still equal, fewer dynamic segments wins (literals beat params)

Changes

• isPathMatchingRoute now returns false | { matchedLength, dynamicSegmentCount } instead of boolean. Existing call sites that only use truthy/falsy semantics are unaffected.
• getCustomViewByRoute (Root) and getCustomCollectionViewByRoute now scan all matches and pick by specificity.
• Added unit specs for both resolvers including registration-order-independence tests.
• Added match-strength tests to isPathMatchingRoute.spec.ts.
• Added e2e coverage in test/admin with new SiblingRootView and SiblingChildView fixtures verifying the rendering at /sibling-root and /sibling-root/:id.
