feat(automations): scheduled cycles, grouped runs, and run details UI

[Kazet111]

Summary

• add a new end-to-end Automations subsystem across backend, database, OpenSpec, and frontend
• add scheduled and manual automation execution with grouped run-cycle tracking
• add cycle snapshot persistence so one automation cycle keeps a stable account set and dispatch plan
• add Jobs and Recent runs views with backend-driven search, filters, and pagination
• add Run details diagnostics with per-account execution state and grouped cycle summaries
• surface automation-generated traffic in Request Logs

Dependency / merge order

This PR includes overlapping changes relative to #415 and should be merged after it.

• merge fix(proxy): harden continuity recovery, safe WS replay, and shutdown/restart bridge lifecycle #415 first
• then rebase this branch on top of main
• then run final CI/review

• Partially addresses Add optional staggered idle warmup for rolling 5h account windows #433

Problem

The project did not yet have a dedicated automations subsystem.

That meant there was no built-in way to:

• define recurring automation jobs
• execute one automation cycle across multiple accounts
• track grouped run state for a cycle
• inspect per-account outcomes within one run
• manage automation jobs and runs from a dedicated UI
• correlate automation traffic with Request Logs

Changes

New backend automations module

• add a dedicated automations API with endpoints for:
  • jobs listing
  • job filter options
  • runs listing
  • run filter options
  • run details
  • create job
  • update job
  • delete job
  • run now (202 Accepted)
• add automations service / repository / scheduler implementation
• add timezone-aware daily scheduling
• add threshold-based dispatch spreading across accounts
• add grouped cycle execution semantics for scheduled and manual runs
• add cycle status resolution for:
  • running
  • partial
  • success
  • failed

Database and run-cycle snapshot model

• add automations schema and base migrations
• add grouped run-cycle snapshot tables:
  • automation_run_cycles
  • automation_run_cycle_accounts
• freeze cycle membership at cycle creation time so later account-state changes do not mutate an already started cycle
• freeze per-account dispatch timestamps for the cycle so threshold edits do not rewrite an in-flight dispatch plan
• backfill legacy manual-cycle history into grouped cycle snapshots
• add model and query support for grouped cycle listing, stable run details, and per-cycle diagnostics

New Automations UI

• add Automations page and route integration
• add Jobs view with backend-driven:
  • search
  • filters
  • pagination
  • rows per page
  • reset
• add Recent runs view with backend-driven:
  • search
  • filters
  • pagination
  • rows per page
  • reset
• add Add automation dialog with:
  • structured form layout
  • validation
  • timezone selection
  • threshold configuration
  • reasoning effort selection
• add Run details modal with:
  • grouped cycle summary metrics
  • per-account execution table
  • mixed-result visibility
  • scalable rendering for larger runs
  • stable grouped diagnostics for scheduled and manual cycles

Request Logs visibility

• wire automation-triggered executions into Request Logs visibility
• make it possible to correlate automation runs with actual downstream requests

OpenSpec

• add and complete the OpenSpec change under openspec/changes/add-automations-scheduled-pings/:
  • proposal
  • design
  • tasks
  • automations delta spec
  • frontend-architecture delta spec
  • context

Result

This PR introduces a new Automations subsystem with scheduling, grouped run cycles, stable cycle snapshots, per-account execution diagnostics, and dedicated UI management flows,
while partially delivering the functionality described in #433.
