feat(sticker): restore customer-name secrecy cover (ABC-MANU)

Body Customer row now prints a 3-and-4 short code instead of the
full company name. Operators see "ABC-MANU" on the floor; visiting
customers / unauthorised passers-by can't immediately tell whose
parts are on which rack.

Rule (per user's reference design):
  - First 3 chars of first word + "-" + first 4 chars of second word
  - Single-word names → just first 3 chars
  - All uppercase
  - Strips non-alphanumeric per word so "St. John's Mfg." doesn't
    leak punctuation into the slice

Logic lives in the shared inner template, so all 4 variants pick
it up automatically:
  sale.order     External + Internal Sticker
  fp.job         External + Internal Job Sticker

Verified on fp.job 2635: Customer row now reads "ABC-MANU" (was
"ABC Manufactoring").

Doesn't use the orphaned x_fc_short_code field on res.partner
(that field has no column or compute — broken Studio remnant).
A future spec can replace this inline computation with a proper
stored+inverse field if customers want per-partner overrides.
