Add equipment manager auto-switching and "Unused" items panel (#70)

* Add equipment manager auto-switching and "Unused" items panel

Equipment manager (modules/equipmentmanager.lua):
- Add automatic set switching: ordered triggers (mounted, swimming,
  eating/drinking, shapeshift form/stance, zone, instance type, time
  of day, resting, stealthed, targeting a boss) equip a set; topmost
  matching trigger wins, with a 0.5s debounce
- Never swap gear in combat, while dead or casting; optionally restore
  the previous gear via a hidden "pfUI Auto-Restore" set
- Add an "Unused" side panel listing equippable items in bags, bank
  and paperdoll that no set uses, with an ignore list (tools and quest
  disguises pre-ignored), bank snapshot and bag highlighting
- Persist triggers, ignore list and bank snapshot in new per-character
  SavedVariable pfUI_eqmgr (all three .toc files)
- Add Character > Equipment Manager options (autoswitch, announce,
  minimum item quality, include bank) in gui.lua and config.lua
- Hide ignored-slot overlays when the manager frame is closed

Add frFR translations for the new equipment manager strings.

* equipmentmanager: lean on ClassicAPI for unused scan and autoswitch

- Unused panel: list items via GetInventoryItemsForSlot instead of
  hand-packing locations and walking the bags.
- Bank snapshot: record set membership while the bank is open.
  GetItemLocations reports bank items as missing once it closes, so set
  items in the bank were listed as unused.
- Autoswitch: check CanUseEquipmentSets and the UseEquipmentSet result
  before marking a trigger applied, and retry when the swap is blocked.
- Drive the engine from events (aura, form, zone, resting, target,
  regen) instead of a 4 Hz ticker; poll only swimming, time and eating.
- Detect eating/drinking by the localized names of the Food (433) and
  Drink (430) auras instead of hardcoded locale strings and icon paths.
- Drop presence guards on APIs that always exist; use strsplittable and
  strtrim for trigger values.

* equipmentmanager: wake the dining trigger on player health/mana events

Drop dining from the poll: listen to UNIT_HEALTH/UNIT_MANA for the player
while a dining trigger is enabled, so taking the set off once full is
event-driven. Register UNIT_AURA for the player only.

* equipmentmanager: split trigger values with strsplit

strsplittable needs ClassicAPI 1.17.11; strsplit has been there since
1.7.3, so this keeps the minimum where it is.

* equipmentmanager: let the trigger hint wrap
