fix(contacts): audit fixes — clip, tofu badge, plural, DPI, columns, toolbar

Address the confirmed findings from a workflow audit of the Contacts tab body:

- Label clip: the Label column was WidthFixed 150px and clipped long labels
  mid-word ("drgx pool payout a…"). Make all three columns WidthStretch (label 1.5,
  address 2.6, notes 1.0) so the label grows with the tab and the notes column no
  longer reserves a fixed empty block on the right (notes = low weight, per request).
- Globe badge tofu: the global-contact ICON_MD_PUBLIC badge was drawn with the text
  font (no Material glyphs) → rendered as "?". Push Type().iconSmall() around it.
- Plural: "1 addresses saved" -> add address_book_count_one ("%zu address saved",
  8 langs, %zu kept so the format signature matches) and branch on count == 1.
- DPI: the SameLine badge gaps (6/8px) and the table-height floor (120px) are now
  * Layout::dpiScale(); the WidthStretch columns are relative so need no scaling.
- Toolbar: give the four actions leading Material icons (person-add / edit / delete /
  content-copy) and accent the primary "Add New" — via a small local icon+label
  tactile-button helper (ImGui has no two-font button), icons inherit the
  disabled-aware text alpha so they gray out with BeginDisabled().

Build + ctest + hygiene clean.
