* feat(server-detail): add online history tab
Render per-server online periods from GET /api/v1/server/:id/online-history:
summary card (current status, online rate, total in window, last active),
daily online-time bars, and the raw period list. Window selector offers
1d/7d/30d and locks options beyond the server's max_days; guests hitting
the 1d cap see a login hint. i18n keys added for all locales (zh-CN/zh-TW
translated, others fall back to English for Weblate).
* fix(online-history): keep selector pills above the sliding indicator
The active-indicator overlay sits at z-10 and intercepted clicks on the
day pills; wrap pills at z-20 like the existing PeriodSelector.
* feat(online-history): render daily online as 24h timeline with hover tooltips
每日在线卡片从整日占比进度条改为 0:00–24:00 整轴时间条：
每个在线时段按当日时刻定位为高亮分段，hover 显示起止时间与时长；
进行中时段以亮色高亮。卡片顶部新增共享刻度（0:00 / 12:00 / 24:00）。
* feat(online-history): regroup periods by day as expandable chip wall
Rework the Online tab per the chip-wall design: periods are grouped by
panel-timezone day with per-day totals, defaulting to the latest day with
"Expand more" revealing up to ten more groups per click, plus an
Online/Offline switch that derives offline chips as the window complement.
- respond to the backend panel timezone (timezone/tz_offset): dayjs 1.11
.tz(input, zone) ignores explicit offsets, so offset-bearing timestamps
are parsed first and converted afterwards; naive date strings keep the
zone-parse path (panelDay)
- guests falling back automatically: a rejected days>1 request locks 7d/30d
and retries at 1d instead of surfacing only a login prompt
- fix day-selector indicator landing on the wrong pill: useActiveIndicator
refs are stored by index, pass the map index not the day value
- disable Node experimental webstorage in vitest workers: Node >=25 ships a
broken global localStorage that shadows the jsdom one
- 14 locales: tabSwitch.Online + serverOnlineHistory.*
* feat(online-history): boxed summary stats with desktop/mobile layouts
* fix(online-history): align offline gaps, DST coordinates and ongoing chips
- extract pure timeline/grouping helpers into src/lib/online-history.ts
- clamp offline complements to day and window boundaries, so a gap can no
longer run into a later day's first online session
- use wall-clock coordinates and true next-midnight boundaries on DST days
- label only the segment ending at the live session end as Ongoing
- keep group totals equal to the visible chips for cross-day sessions
- keep period chips on one line and render next-midnight as 24:00
- add regression tests for multi-day offline gaps, window_start/window_end,
spring-forward/fall-back geometry and ongoing clipping
* style(online-history): lighten summary metrics and shorten rate bar
* feat(online-history): refine UI and unify daily history rendering
