The concurrency / switch-rate / throughput cards on the ops dashboard
sit in grid cells that only set `min-h-[360px]` (no definite height).
Their inner card uses `h-full`, which resolves to `auto` when the parent
height is `auto`. Combined with the Chart.js `responsive` +
`maintainAspectRatio: false` charts, this forms a height feedback loop:
the canvas reads the parent height to size itself, the content then grows,
the next ResizeObserver tick reads an even larger height, and the cards
stretch downward without bound.
On wide screens (`lg:grid-cols-4`) a sibling card usually fixes the row
height via `align-items: stretch`, masking the issue. It surfaces when no
sibling bounds the row height — e.g. the single-column (`grid-cols-1`)
stacked layout on narrow viewports, or when the concurrency card collapses
to little content. `min-h` only sets a floor, not a ceiling.
Fix: give the two Chart.js canvas cells a definite height (`h-[360px]`) so
the responsive resize has a fixed reference and the loop cannot run. The
concurrency card is not a responsive canvas, so it keeps `min-h-[360px]`
to avoid clipping its content.

- gate previous_response_id sticky path with quota auto-pause check at both
the snapshot and DB-recheck stages (previously bypassed, #1)
- skip pausing when the usage window already reset to avoid a stale stuck-pause;
carry codex_*_reset_at / reset_after_seconds / codex_usage_updated_at through
the scheduler snapshot whitelist (#2)
- remove the incomplete limit mode; percentage threshold only (#3)
- add global default 5h/7d threshold inputs to the Ops settings dialog with
validation and en/zh i18n (#4)
- downgrade account_auto_paused_by_quota log from Info to Debug; it fires
per-candidate on the scheduling hot path (#5)

Background / 背景
The ops cleanup task currently rejects retention days < 1 in both validate
and normalize, so operators who want minimal-history setups (e.g. high
churn deployments that prefer near-realtime cleanup) cannot express that
intent through the UI. The only options are 1+ days, which keeps at least
24h of history regardless of cron frequency.
ops 清理任务目前在 validate 和 normalize 两处都拒绝小于 1 的保留天数，
让希望尽量不留历史的运维场景（高吞吐部署 + 想用近实时清理）无法通过 UI
表达。最低只能配 1，等于不管 cron 多频繁，至少都会保留 24 小时的历史。
Purpose / 目的
Let admins set retention days to 0, meaning "every scheduled cleanup
run wipes the corresponding table(s) entirely". Combined with a more
frequent cron (e.g. `0 * * * *`) this yields effectively rolling cleanup.
允许管理员把保留天数设为 0，语义为"每次定时清理时把对应表全部清空"。
搭配更频繁的 cron（比如每小时整点）即可获得近似滚动清理的效果。
Changes / 改动内容
Backend
- service/ops_settings.go: validate accepts [0, 365]; normalize only
refills default 30 when value is < 0 (negative is treated as legacy
bad data, 0 is honoured)
- service/ops_cleanup_service.go: introduce `opsCleanupPlan(now, days)`
returning `(cutoff, truncate, ok)`. days==0 returns truncate=true and
short-circuits to a new `truncateOpsTable` helper that uses
`TRUNCATE TABLE` (O(1), no WAL, no VACUUM pressure). days>0 keeps
the existing batched DELETE path unchanged. Empty tables skip
TRUNCATE to avoid the ACCESS EXCLUSIVE lock entirely
- Extract `isMissingRelationError` helper to dedupe the "table not
yet created" tolerance shared by both delete and truncate paths
- Add unit tests for `opsCleanupPlan` (three branches) and
`isMissingRelationError`
后端
- service/ops_settings.go: validate 接受 [0, 365]；normalize 仅在 < 0
时回填默认 30（负数视为脏数据，0 被尊重）
- service/ops_cleanup_service.go: 抽 `opsCleanupPlan(now, days)` 返回
`(cutoff, truncate, ok)`。days==0 → truncate=true，走新增
`truncateOpsTable`（TRUNCATE TABLE，O(1)，无 WAL、无 VACUUM 压力）；
days>0 仍走原批量 DELETE 路径，行为完全不变。空表跳过 TRUNCATE，
避免无意义的 ACCESS EXCLUSIVE 锁
- 抽 `isMissingRelationError` helper 复用 delete / truncate 两处的
"表不存在"宽容判断
- 补 `opsCleanupPlan` 三分支 + `isMissingRelationError` 单元测试
Frontend
- OpsSettingsDialog.vue: validation accepts [0, 365]; input min=0
- i18n (zh/en): hint mentions "0 = wipe all on every cleanup",
validation message updated to 0-365 range
前端
- OpsSettingsDialog.vue: 校验放宽到 [0, 365]，input min 改 0
- i18n（zh/en）：hint 补"0 = 每次清理时清空所有"，错误提示改 0-365
Trade-offs / 取舍
- TRUNCATE requires ACCESS EXCLUSIVE lock briefly, but ops tables only
have the cleanup task as a writer, so the lock is invisible to other
workloads
- Empty-table guard avoids the lock when there is nothing to clean
- Negative values are still treated as legacy bad data and replaced
with default 30 to preserve compatibility
- Add 5th error filter switch IgnoreInsufficientBalanceErrors to suppress
upstream insufficient balance / insufficient_quota errors from ops log
- Extract hardcoded error strings into package-level constants for
shouldSkipOpsErrorLog, normalizeOpsErrorType, classifyOpsPhase, and
classifyOpsIsBusinessLimited
- Define ErrNoAvailableAccounts sentinel error and replace all
errors.New("no available accounts") call sites
- Update tests to use require.ErrorIs with the sentinel error
Merge functional changes from develop branch:
- Remove AntigravityQuotaScope system (claude/gemini_text/gemini_image)
- Replace with per-model rate limiting using resolveAntigravityModelKey
- Remove model load statistics (IncrModelCallCount/GetModelLoadBatch)
- Simplify account selection to unified priority→load→LRU algorithm
- Remove SetAntigravityQuotaScopeLimit from AccountRepository
- Clean up scope-related UI indicators and API fields
