refactor(ui): Deduplicate wallet/transactions pages — ledger merged into Transactions

[argszero]

Summary

Deduplicate the Wallet and Transactions pages per host instruction (rant 2026-08-14T15:59:09, 方案 A — merge): the Wallet page previously rendered the same data (D.TRANSACTIONS) with nearly identical columns as the Transactions page, causing user confusion.

Changes

• Wallet page (view-wallet): removed the 收支明细 Ledger table (wallet-table); now shows only the balance card (points balance + Top up / Withdraw buttons) plus a hint line linking to Transactions (#wallet-goto-tx).
• Transactions page (view-transactions): remains the single detail entry — Tabs (全部/消费/收益) + MRT table (sort/filter/pagination) unchanged; subtitle expanded to cover 消费（用别人的 key）、收益（别人用我的 key）、充值、提现.
• Code cleanup: removed WALLET_COLUMNS and the walletTable state; renderWallet now renders balance/buttons only; data.js comment updated (no longer wallet 与 transactions 共用); ui/README.md synced.
• Dashboard untouched (recent-transactions snapshot kept).

Note: the rants suggested continuing on PR #7's branch, but PR #7 was already merged (d70e032) — these are follow-up UI iterations submitted as a new PR against main.

Follow-up 1 (commit 9aef59a, rant 2026-08-14T16:01:35)

• Wallet Top up / Withdraw buttons are now disabled (置灰) with a "充值 / 提现暂不支持（即将上线）" note — per host instruction these fund operations are not supported yet.
• ui/js/app.js: removed the now-dead toast handlers for the disabled buttons; #wallet-goto-tx link remains.

Follow-up 2 (commit d1d3a77, rant 2026-08-14T16:03:11)

• Admin → Employees: the fixed "+5000 点" button is replaced with a 充值 (Top up) action that prompts for an arbitrary positive integer amount; invalid input (empty / non-integer / ≤0) is rejected with a toast and no change is applied.
• After a successful topup: employee list + stats (总配额 / 剩余) refresh, success toast shows "已给 {name} 充值 {amount} 点".

Follow-up 3 (commit 801e78c, rant 2026-08-14T16:08:54)

• Admin → Org management (组织管理): added a department list (部门名 / 成员数 / 月分配点数 / 已用 / 剩余 / 状态) with a summary stat grid (部门数 / 月度总分配 / 已用 / 剩余).
• Department CRUD: 添加部门 (prompt for name + positive-integer monthly quota, duplicate-name rejected), 编辑 (rename + adjust quota; employee dept fields follow renames), 删除 (confirmation; if the dept has members the confirm warns "该部门有 N 名成员"), 查看 via name search/filter.
• Data linkage: data.js adds DEPARTMENTS mock (研发/产品/市场/设计 with monthly quota); used/member-count are aggregated live from EMPLOYEES so stats stay consistent.
• The existing 组织设置 card is kept below the department list on the same page.

Tests

• node --check passes on ui/js/app.js and ui/js/data.js
• No residual wallet-table / WALLET_COLUMNS / walletTable / data-emp-add references
• Dept aggregation sanity-checked in Node (members/used/quota/remain per dept + totals)
• cargo test passes (1 passed)

Follow-up 4 (commit d72389a, rants 2026-08-14T16:10:26 + 2026-08-14T16:11:11)

• Member dept change (改部门): each employee row now has a 改部门 action (next to 充值) that opens an inline dropdown in the dept cell; options come live from DEPARTMENTS plus an 未分配 (unassigned) entry; confirm updates the employee's dept and refreshes the list/stats with a toast ("已把 {name} 调整到 {dept} 部门 / 未分配").
• Unassigned-dept model (新成员默认不属于任何部门): employee dept may now be empty — rendered as a gray 未分配 placeholder; mock EMPLOYEES gains two unassigned new-registration members (赵欣, 王磊); the 改部门 dropdown can remove a member from any dept (set 未分配); department member-count/used stats exclude unassigned members (org pane shows "未分配 N 人" when any), and the employees stat grid now shows a dynamic dept count + unassigned count; top-up works for unassigned members as before (not dept-dependent).

Follow-up 5 (commit 18827ac, rant 2026-08-14T16:14:33)

• Settings → API Key full CRUD: the API key list became a table (名字 / Key / 创建时间 / 最近使用 / 状态 / actions) with a name search filter.
• Create: "生成新 Key" prompts for a name (blank → "未命名"); generates a full atk_live_<hex> id stored in the mock (previously the mock itself stored a truncated id).
• Read/display: keys are shown masked (atk_live_****xxxx) while the full id lives in the data.
• Copy: per-row 复制 uses navigator.clipboard.writeText(full id) with a graceful fallback for file:// (temp textarea + execCommand("copy"); if that fails, text is selected and a "Ctrl/Cmd+C" hint toast shows) — success toast "已复制…完整 key 到剪贴板".
• Update: per-row 改名 prompts for a new non-empty name.
• Delete: per-row 删除 confirms "删除后该 key 立即失效" then removes the key.
• ui/README.md updated to mention API Key management capabilities.
