[BUG] Captured path segments are not URL-decoded in ZIO HTTP + Captured path segments don't treat '+' properly in finatra and vertx

[finalchild]

Tapir version: 1.9.4

Scala version: 3.3.1

Describe the bug

What is the problem?

1. Captured path segments should be URL-decoded, but it's not only in ZIO HTTP. See [BUG] Captured path segments are not URL-decoded #896 and fix(server): URL-decode captured path segments #1062.

Behavior when using Vert.X: (correct)

Behavior when using ZIO HTTP: (wrong)

2. Captured path segments should not treat '+' as ' '. (This "plus as space" behavior is specific to query strings and doesn't extend to path strings.) This is a bug introduced in fix(server): URL-decode captured path segments #1062.

Behavior when using http4s: (correct)

Behavior when using Vert.X: (wrong)

Finatra upstream has this bug too: twitter/finatra#590
