Add built-in filament name lookup table for nozzle rack and AMS tooltips (#300)

The Bambu Cloud API returns 400 for many filament IDs (e.g. GFB01,
GFU99, GFL99), causing nozzle rack hover cards to fall back to
abbreviated tray_type values ("ASA", "TPU", "PLA") instead of full
names.

Added a built-in lookup table of 86 known Bambu filament codes as a
Phase 4 fallback in get_filament_info. Resolution order is now:
cache → cloud API → local profiles → built-in table → empty fallback.

GFB01 → "Bambu ASA", GFU99 → "Generic TPU", GFL99 → "Generic PLA",
etc. Also benefits AMS tray tooltips for unresolvable filament IDs.

@@ -23,7 +23,7 @@ All notable changes to Bambuddy will be documented in this file.
 - **H2 Series — Single-Nozzle Hover Card** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — H2D/H2S printers with a single nozzle now show extended nozzle details (wear, serial, max temp) on hover over the temperature card. Backend changed from H2C-only (>2 nozzles) to all H2 series (any nozzle_info present).
 - **H2C Nozzle Rack — Translate Type Codes & Add Flow Info** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — Raw nozzle type codes (e.g. "HS", "HH01") are now translated to human-readable names: material (Hardened Steel, Stainless Steel, Tungsten Carbide) and flow type (High Flow, Standard). New "Flow" row in the hover card. Translations added in all 4 locales (en, de, ja, it).
 - **H2C Nozzle Rack — Show Filament Material in Hover Card** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — Nozzle hover card now shows the loaded filament material type (e.g. "PLA", "PETG") alongside the color swatch, captured from MQTT nozzle info data.
-- **H2C Nozzle Rack — Resolve Filament Names From Cloud & Local Profiles** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — Nozzle rack hover card previously showed raw filament IDs like "GFU99" instead of human-readable names. Now resolves filament names with a 3-tier fallback: Bambu Cloud preset lookup → local slicer profiles (matching by `setting_id` in the imported OrcaSlicer JSON) → raw ID fallback. Uses the same cloud lookup mechanism as AMS trays. Local profiles work without cloud authentication for users who import their slicer presets.
+- **H2C Nozzle Rack — Resolve Filament Names From Cloud & Local Profiles** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — Nozzle rack hover card previously showed raw filament IDs like "GFU99" instead of human-readable names. Now resolves filament names with a 4-tier fallback: Bambu Cloud preset lookup → local slicer profiles → built-in filament name table (86 known Bambu filament codes) → raw ID fallback. The built-in table resolves names like "Bambu ASA", "Generic TPU", "Generic PLA" when the cloud API returns 400 for certain filament IDs. Also benefits AMS tray tooltips.
 - **H2C Nozzle Rack Compact Layout** ([#300](https://github.com/maziggy/bambuddy/issues/300)) — Redesigned nozzle rack from a 2×3 grid to a compact single-row layout with bottom accent bars (green = mounted, gray = docked). Temperature cards are thinner, rack card is wider (flex-[2]), and all cards vertically centered.
 - **Firmware Version Badge on Printer Card** ([#311](https://github.com/maziggy/bambuddy/issues/311)) — Printer cards now show a firmware version badge (when firmware checking is enabled). Green with checkmark when up to date, orange with download icon when an update is available. Clicking the badge opens a firmware info modal showing release notes (auto-expanded when up to date) or the existing update workflow. Badge and modal respect `firmware:read` and `firmware:update` permissions. Translations added in all 4 locales.
 - **Auto-Detect Subnet for Printer Discovery** — Docker users no longer need to manually enter a subnet in the Add Printer dialog. Bambuddy auto-detects available network subnets and pre-selects the first one. When multiple subnets are available (e.g., eth0 + wlan0), a dropdown lets users choose. Falls back to manual text input if no subnets are detected.
