chore(libs): sync Ace3 to coa-ace3 d422ad3

Aligns the unsuffixed Ace bundle with the rest of the Exiles forks
(the -ElvUI namespaced copies are intentionally left alone to keep
ElvUI's config UI isolated from any other addon's LibStub registrations).

Per-library MINOR moves:
  CallbackHandler-1.0   6  →  8
  AceAddon-3.0         12  → 13
  AceTimer-3.0       1017  → 17  (canonical numbering — same C_Timer impl)
  AceHook-3.0           8  →  9
  AceDB-3.0            27  → 33
  AceDBOptions-3.0     15  → 15  (unchanged)
  AceComm-3.0          12  → 14
  AceSerializer-3.0     3  →  5

Other Ace libs (Event, Config family, GUI, Locale, Console, Bucket) were
already at the canonical target.
