Add FBI most-wanted MISP object template

[adulau]

Motivation

• Provide a MISP object template that models FBI Most Wanted entries (as available from the FBI Wanted API v1) to allow ingestion and sharing of wanted-person metadata.
• Address the feature request described in issue Create an object template from the most-wanted fbi record #67 by mapping common FBI entry fields (identifiers, biographical descriptors, classification/status, resources) to MISP attributes.

Description

• Added a new object template at objects/fbi-most-wanted/definition.json which models FBI API v1 fields such as uid, title, legal-name, alias, images, files, publication, modified, field-office, reward-text, and physical descriptors (height, weight, hair, eyes, scars-and-marks).
• Declared uid and title as required attributes so each instance has a stable identifier and display label.
• Set meta-category, name, uuid, and version for integration with the misp-objects collection and tuned ui-priority, multiple, and disable_correlation flags for appropriate attributes.
• Ran the repository formatting/normalization step via ./jq_all_the_things.sh to canonicalize JSON output.

Testing

• Ran ./jq_all_the_things.sh to normalize JSON formatting and it completed in this environment.
• Attempted ./validate_all.sh but it did not finish because the validation workflow requires a clean working tree and some helper tools are missing in this environment, so full end-to-end validation did not complete.
• Attempted jsonschema validation but the jsonschema tool was not available (jsonschema: command not found), so schema validation could not be executed here.
