refactor(core): Eliminate XxxProvider enums

[gtema]

Replace 13 XxxProvider enums (with Service/Mock variants and delegation
impls) with Box trait objects in Provider. Consolidate
13 mock.rs files into single mocks.rs with all mock! definitions.

This removes ~3300 lines of repetitive enum, delegation, and per-module
mock boilerplate. Provider fields are now Box, builder
accepts impl XxxApi for mock injection, and getters return trait refs.

This also slightly improves the compilation time (roughly 60%)
