fix(apps): make db --environment optional, auto-select branch server-side

All db shortcuts defaulted --environment to "dev", which forced single-env
apps (whose DB lives on the online branch, with no dev branch) to fail with
"Invalid DB Branch: dev" unless the user explicitly passed --environment
online.

Change the default to empty: when --environment is omitted the CLI sends no
env, letting the server pick the branch by the app's multi-env state
(multi-env → dev, single-env → online), matching miaoda-cli's behavior of
not carrying dbBranch when unset. Explicit --environment dev|online is
unchanged; explicit dev on a single-env app still errors as expected.

- 10 db shortcuts: dbEnvFlags default "dev" → "" (+db-execute, +db-table-list,
  +db-table-get, +db-quota-get, +db-data-export, +db-data-import,
  +db-changelog-list, +db-audit-list/-set/-status)
- dry-run e2e assertions updated: default env is now unset, not "dev"
- skill docs (lark-apps-db, lark-apps-db-execute) describe the auto-select

 - **不会自动为你包事务，事务边界需自己在 SQL 里控制**：多语句默认逐条独立提交，中间某条失败时前序语句已生效、不会回滚；若需要「要么全部成功、要么全部回滚」的原子性，请在 SQL 内显式写 `BEGIN … COMMIT`（详见下「Agent 规则」）。

+`+speaker-replace` **不会**自己请求 speakerlist：`--from-speaker-id` 的值会原样发给替换接口。整条链路只在 Agent 一开始查一次 speakerlist，务必传入上一步拿到的 `speaker_id`（不要传展示名，否则替换接口会返回 speaker-not-found）。
