fix(chart): apply hasKey to remaining boolean defaults for consistency

[chaodu-agent]

What problem does this solve?

PR #639 fixed the | default true trap for enabled fields, but two | default false fields were left unchanged:

• remove_after_reply = {{ ($cfg.reactions).removeAfterReply | default false }}
• usercron_enabled = {{ (($cfg.cron).usercronEnabled) | default false }}

While {{ false | default false }} happens to produce the correct result today, it creates a latent trap — if anyone changes the default to true in the future, the same false-is-zero-value bug would resurface silently.

Flagged during triage review of PR #639.
