Add missing nil argument for rpmCache to NewAccountHandler (5 sites)
and NewGatewayService (2 sites) after RPM feature expanded their
signatures.

Ensures base_rpm validation (clamp 0-10000) is consistent across
all four account mutation paths: Create, Update, BulkUpdate, BatchCreate.

- Add sanitizeExtraBaseRPM to BulkUpdate handler (was missing)
- Add WindowCost scheduling checks to legacy non-sticky selection
  paths (4 sites), matching existing sticky + load-aware coverage
- Export ParseExtraInt from service package, remove duplicate
  parseExtraIntForValidation from admin handler

- Move IncrementRPM after Forward success to prevent phantom RPM
  consumption during account switch retries
- Add base_rpm input sanitization (clamp to 0-10000) in Create/Update
- Add WindowCost scheduling checks to legacy path sticky sessions
  (4 check sites + 4 prefetch sites), fixing pre-existing gap
- Clean up rpm_strategy/rpm_sticky_buffer when disabling RPM in
  BulkEditModal (JSONB merge cannot delete keys, use empty values)
- Add json.Number test cases to TestGetBaseRPM/TestGetRPMStickyBuffer
- Document TOCTOU race as accepted soft-limit design trade-off

Without this, submitting a bulk edit with only RPM changes would be
rejected as "no fields selected".

Ensures isAccountSchedulableForRPM calls within the routing segment
hit the prefetch cache instead of querying Redis individually.

- Use TxPipeline (MULTI/EXEC) instead of Pipeline for atomic INCR+EXPIRE
- Filter negative values in GetBaseRPM(), update test expectation
- Add RPM batch query (GetRPMBatch) to account List API
- Add warn logs for RPM increment failures in gateway handler
- Reset enableRpmLimit on BulkEditAccountModal close
- Use union type 'tiered' | 'sticky_exempt' for rpmStrategy refs
- Add design decision comments for rdb.Time() RTT trade-off

fix(ci): 修复 gosec 扫描因 ent 生成代码导致超时的问题

【问题描述】
backend-security CI job 持续运行约 6 小时后被 GitHub Actions 强制取消，
表现为 'Run gosec' 步骤挂起，最终以 cancelled 状态结束。

【根本原因】
gosec 对 ./... 执行 AST 静态分析时，包含了 ent/ 目录下的
自动生成文件（如 mutation.go 共 24800 行），导致分析时间
超出 GitHub Actions 默认的 6 小时上限。

【修复方案】
1. gosec 命令增加 -exclude-dir=ent 跳过自动生成代码目录
2. backend-security job 增加 timeout-minutes: 15，避免未来
   类似问题再次长时间卡死后才被发现

ent/ 目录内容全部由 Ent ORM 框架自动生成，开发者不直接编写，
不需要纳入人工安全审计范围，排除后不影响扫描有效性。

fix: add 2K image default pricing at 1.5x base price

fix(frontend): add priority hint in edit account modal

Previously 2K images used the same base price as 1K ($0.134).
Now 2K uses 1.5x multiplier ($0.201), consistent with 4K using 2x ($0.268).

- Backend: add 2K size branch in getDefaultImagePrice
- Frontend: update 2K placeholder from 0.134 to 0.201
- Tests: update assertions for new 2K default price

fix: update antigravity user-agent version to 1.19.6

feat: 新增 gemini-3.1-flash-image 支持，替代 gemini-3-pro-image

Update the default user-agent version from 1.18.4 to 1.19.6
to match the latest official antigravity client.

- Add migration 060 to update model_mapping for all antigravity accounts
- Remove gemini-3-pro-image and gemini-3-pro-image-preview mappings
- Add gemini-3.1-flash-image and gemini-3.1-flash-image-preview mappings
- Update frontend usage window to show GImage for new model
- Update isImageGenerationModel to support new model

fix(frontend): 批量编辑添加跨平台模型映射警告与智能过滤

fix(gateway): count_tokens 不支持时返回 404 而非伪造的 200

PR #635 returned HTTP 200 with {"input_tokens": 0} when upstream doesn't
support count_tokens (404). This caused Claude Code CLI to trust the zero
value, believing context uses 0 tokens, so auto-compression never triggers.

Fix: return 404 with proper error body so CLI falls back to its local
tokenizer for accurate estimation. Return nil (not error) to avoid
polluting ops error metrics with expected 404s.

Affected paths:
- Passthrough APIKey accounts: upstream 404 now passed through as 404
- Antigravity accounts: same fix (was also returning fake 200)

- useModelWhitelist.ts 添加 gpt-5.3-codex、gpt-5.3-codex-spark
- BulkEditAccountModal.vue 添加 5.3 模型选项与预设按钮（含 5.2→5.3 升级映射）
