refactor(presets): align CCSub to end of partner block across apps

Move the CCSub preset to sit right after DouBaoSeed, at the end of the
partner block and before the first non-partner provider, so its position
is consistent across all six apps:

- Codex / OpenCode: moved up from the 2nd slot (between Shengsuanyun and
  the next partner) to the block tail
- OpenClaw / Hermes: moved up from the aggregator section to the block tail
- Claude / Claude Desktop: already at the block tail

Also add the missing CHANGELOG entry for the CCSub preset, and drop the
provider preset order test that enforced a now-unneeded ordering invariant.
