fix(agent): initialize plugins before resolving config

Plugin config() hooks can mutate the agent registry. Agent.Service
was snapshotting config before plugin init ran on early entry points
like GET /agent, so plugin-provided agents were missing in the TUI
agent picker after upgrading to v1.14.32.

Re-submission of #25440 (auto-closed by template bot) with proper PR
template. Original fix by @quangtran88.
