fix(nexa_coa_setup): clean GL codes — 119100/119900->115200/115900, 511105->511100

Three odd code positions that were chosen to dodge l10n_ca collisions are
now cleaned up:
- Due From Shareholder       119100 -> 115200 (115xxx is where receivables belong)
- Due From Associated Corps  119900 -> 115900
- Cloud Infrastructure       511105 -> 511100 (legacy 'Inside Purchases'
                                       renamed to 511100.OLD)

Applied to prod via scripts/fix_gl_codes.py (now committed).

Module XML updated: <field name='code'> values match new codes; XMLIDs
(acct_119100, acct_119900, acct_511105) preserved so existing
ir.model.data rows on prod still map to the right records.

pre_init_hook augmented with _L10N_CA_FORCE_CLEAR_CODES set so a fresh
install on a new DB also force-clears 511100 (which would otherwise be
blocked by the postings-exist guard).
