pack: full CC recipe overhaul — 19 items across 5 progression tiers

Expands the v0.19.0 recipe set from 10 to 19 items and builds a deliberate
5-tier progression using richer Create + TFMG materials.

Newly overhauled items:
  T1 - cable (8-output, copper_wire-heavy so bulk-laying is viable)
  T3 - redstone_relay
  T3 - turtle_normal
  T4 - turtle_advanced
  T5 - pocket_computer_normal, _advanced, _colour
  Misc - wired_modem_full (block form, derived from wired_modem)

Existing items reworked with better thematic materials:
  computer_normal/advanced  -> now uses create:brass_casing / railway_casing
                                as the chassis instead of bare plastic
  monitor_normal/advanced   -> nixie_tube for the retro CRT, display_link
                                for the advanced data-binding monitor
  wireless_modem_normal     -> tfmg:electromagnetic_coil is the antenna,
                                copper_wire + aluminum_wire signal lines
  wireless_modem_advanced   -> constantan_spool + large_coil for high-Q
                                tuning -- properly end-game wireless
  disk_drive                -> create:cogwheel for the spinning read head
  speaker / printer         -> copper_sheet / cogwheel for thematic flair

Wire usage is the through-line: copper_wire in T1-T2 (cheap, used in
quantity), aluminum_wire in T3 mid-tier signal lines, constantan_wire
+ constantan_spool in T4 for high-frequency wireless. TFMG's electrical
production now genuinely gates CC progression.

Bumps pack to 0.19.1 (point release — same mod set, expanded scripts).
