chore: removed types deprecated

[Tony133]

Proposal:

• Remove deprecated compress and decompress properties from route config.

Changed

• Removed FastifyContextConfig interface (deprecated)
• Removed RoutesConfigCompressOptions interface (deprecated)
• Removed legacy routeOptions.config.compress / routeOptions.config.decompress fallback logic in index.js
• Removed related tests for the old { config: { compress/decompress } } pattern

These options were deprecated in favour of the shorthand compress/decompress route options.

Note:

• Release a major version of the plugin after this pull request has been merged
