fix(ui): fill remaining gaps in payload-type lookup tables (10/11/15) (#967)

## Summary

Fill the remaining gaps in payload-type lookup tables noted out-of-scope
on #965. Every firmware-defined payload type (0–11, 15) now has entries
in all four frontend tables.

## Changes

Three types were missing from one or more tables:

| Type | Name | `PAYLOAD_COLORS` (app.js) | `TYPE_NAMES` (packets.js) |
`TYPE_COLORS` (roles.js) | `TYPE_BADGE_MAP` (roles.js) |

|------|------|--------------------------|--------------------------|-------------------------|---------------------------|
| 10 | Multipart | added | added | added `#0d9488` | added |
| 11 | Control | added | ✅ (already) | added `#b45309` | added |
| 15 | Raw Custom | added | added | added `#c026d3` | added |

## Color choices

- **MULTIPART** `#0d9488` (teal) — multi-fragment stitching, distinct
from PATH's `#14b8a6`
- **CONTROL** `#b45309` (amber) — warm brown, distinct hue from ACK's
grey `#6b7280`
- **RAW_CUSTOM** `#c026d3` (fuchsia) — magenta, distinct from TRACE's
pink `#ec4899`

All pass WCAG 3:1 contrast against both white and dark (#1e1e1e)
backgrounds.

## Tests

- `test-packets.js`: 82/82 ✅
- `test-hash-color.js`: 32/32 ✅

Badge CSS auto-generation: `syncBadgeColors()` in `roles.js` iterates
`TYPE_BADGE_MAP` keyed against `TYPE_COLORS`, so the three new entries
automatically get `.type-badge.multipart`, `.type-badge.control`, and
`.type-badge.raw-custom` CSS rules injected at page load.

Firmware source: `firmware/src/Packet.h:19-32` — types 0x00–0x0B and
0x0F. Types 0x0C–0x0E are not defined.

Follows up on #965.
