profiles: deterministic setting_id from vendor/type/name (#14432)

* profiles: enforce globally-unique, per-vendor-namespaced setting_id

Many non-Bambu vendors copied Bambu's generic setting_ids (GFSA04 alone
appeared in 1557 files), so setting_id was not globally unique. This
namespaces every vendor's ids and reserves Bambu/OrcaFilamentLibrary space.

- Reserve "G*" (Bambu) and "O*" (OrcaFilamentLibrary) id spaces.
- Assign each other vendor a 2-char prefix (first+last letter, collision
  resolved) and renumber every instantiated preset to <PREFIX><NNNN>.
- Strip setting_id from base profiles (instantiation:false) per Bambu's
  convention; assign one to instantiated presets that lacked it.
- Remove the pre-existing misspelled "settings_id" key (91 files).
- filament_id is left untouched (it is a per-material id).
- Add one-time migration script scripts/assign_vendor_setting_ids.py with a
  persisted registry resources/profiles/vendor_prefixes.json. Re-runs freeze
  existing ids; only new vendors/profiles get new ids.
- Bump version in each changed vendor index file.
- Extend scripts/orca_extra_profile_check.py with a CI guard: global
  uniqueness, in-namespace, no base setting_id, no gaps, no settings_id typo.

7425 profile files changed across 61 vendors; 0 cross-vendor collisions;
validator clean; migration idempotent. BBL and OrcaFilamentLibrary id spaces
untouched.

* profiles: add setting_id authoring guide for new vendors / profiles

* profiles: drop in-repo README; setting_id guide now lives in the wiki

* profiles: derive setting_id deterministically from vendor/type/name

* bump profile version
