improve: add filter parameter to compute list tools

[cavramoniu-ionos]

Summary

• Added an optional filters parameter to all compute list_* tools in the MCP server. Filters are forwarded as server-side query params (filter.{key}={value}), so only matching resources are returned by the API - no client-side post-processing needed.
• New dedicated input structs (ListInDatacenterInput, ListInServerInput, and 7 resource-scoped variants) keep get_* tool schemas clean - filter fields don't bleed onto single-resource GET tools.
• All Filters field descriptions include a retry hint: if a filter returns an empty result, the model retries without filters since a typo or value mismatch silently returns nothing.

Pull request overview

Adds an optional filters input to Compute Engine list_* MCP tools and forwards those filters to the IONOS Compute API as filter.{key}={value} query params, enabling server-side filtered listings (and reducing the need for client-side post-processing).

Changes:

• Extended compute list-tool input schemas with filters (and introduced resource-scoped list input structs to avoid affecting get_* schemas).
• Updated compute list_* tool implementations to apply Filter(k, v) on the SDK request builders before Execute().
• Expanded endpoint routing tests and updated compute docs + changelog to reflect the new parameter.
