#55 Describe connecting with the trial in one step

Updates the Console monitoring, connect, and CLI docs for dagucloud/dagu#3287 and dagucloud/cloud#41:

• Plan & features has one connect card, with an optional 14-day trial in the same approval.
• A trial gets everything a plan's monitoring does, and owners get emails before it ends.
• Dagu picks up a new trial when you return from Console, or on the server's next report.
• A connect request waits an hour.
• dagu license activate takes --report.

pnpm build passes, including the dead-link check.

Summary by cubic

Updates the Console monitoring, connect, and CLI docs for the new one-step connection flow. Connecting a server on Plan & features can now start the 14-day trial in the same approval, instead of as a separate step.

• A trial gets everything a plan's monitoring does; workspace owners get an email three days before it ends and another when it ends.
• Dagu picks up a new trial when you return from Dagu Console, at the server's next report, or at its next hourly check-in.
• A connect request now waits up to an hour for approval.
• dagu license activate now takes --report on Dagu v2.22 or later, with a prompted choice when the flag is absent.
• Trial run history is now 30 days, matching Team and Pro; free monitoring stays at 7.
