i18n(mod-tools): route every label/title/placeholder through LocalizeText

The ModTools template refresh introduced ~80 hardcoded English strings
(labels, placeholders, tooltips, empty-state copy, button text). Move
every one of them onto the modtools.* namespace and read via
LocalizeText so the panels translate alongside the rest of the client.

UITexts.example (versioned template) extended with the full set:

  modtools.window.*            Launcher box (toolbar item, tools,
                               selected-user state, ticket count)
  modtools.userinfo.*          User info card — already had the
                               legacy modtools.userinfo.{userName,
                               cfhCount, …} keys from before; added
                               refresh tooltip, presence pill labels
                               (in_room / online / offline with
                               matching .title tooltips), section
                               headings, action button labels, stat
                               card labels
  modtools.roominfo.*          Room info card — title, refresh, loading,
                               owner pill (here/away + tooltips), stat
                               labels, action buttons, moderate panel
                               heading + checkboxes + textarea
                               placeholder + caution/alert CTAs
  modtools.user.message.*      Send-message dialog (recipient label,
                               body label, placeholder, char counter,
                               empty state, send button)
  modtools.user.modaction.*    Mod Action form — header, sanctioning
                               label, 3-step section titles, select
                               placeholders, message label + optional
                               note, message placeholder, preview
                               heading, default/apply buttons, every
                               sendAlert error message
  modtools.user.visits.*       Room visits — title, header strip
                               heading, entry count (singular/plural),
                               empty state, column headers, visit
                               button + tooltip
  modtools.user.chatlog.*      User chatlog — title (with username
                               variant), loading state
  modtools.room.chatlog.*      Room chatlog title
  modtools.chatlog.*           Shared ChatlogView — column headers,
                               empty state, room-separator Visit/Tools
                               buttons
  modtools.tickets.*           Tickets window — title, tab labels
                               (open/mine/picked), column headers,
                               empty states, action buttons (pick/
                               handle/release), issue resolution
                               window (title, label, details heading,
                               field labels, chatlog toggle, resolve-as
                               heading, resolution buttons, release
                               back to queue), CFH chatlog title

The same 130 entries land in Nitro-Files/.../UITexts.json (runtime).
Both files validate as JSON. The runtime additions take effect on
next client reload; the template additions ship the strings to any
fresh deploy.

Notes:
  - The MOD_ACTION_DEFINITIONS sanction names ("Alert", "Mute 1h",
    "Ban 18h" …) stay hardcoded for now since they're keyed off
    server-side action IDs that don't have an existing locale key
    convention. Worth a follow-up if needed.
  - help.cfh.topic.* keys (CFH topic display names) are already in
    ExternalTexts.json and were already read via LocalizeText, so
    they didn't need changes.

typecheck + vitest 214/214 + lint:hooks all clean.
