web: add the notification render limits to the notify settings page

PR #172 made the summary length and the number of assets listed in an IM
message configurable, but only through the API. The Notifications page now
shows both next to the other global settings:

  Summary length (characters)   notify_summary_max_runes   0-4000
  Assets listed per finding     notify_assets_max_shown    0-50

The values are read from GET /api/settings (they are not part of
/notify/meta) and saved with the existing "Save global settings" PUT.
Each field carries a help text stating that 0 means no truncation.

A value that is not a whole number within the bounds marks the input
invalid and blocks the save with a toast. The check runs before the
request because the backend applies the fields of one PUT in order, so a
400 on a limit would leave the URL and digest interval already saved. An
empty field is not submitted and keeps the stored value.
