Fix Fuzzy Match algorithm dropdown and distance measure type

[leehaut]

Summary

• Exclude the empty NONE option from the Fuzzy Match algorithm dropdown so the first selectable row is a real algorithm.
• Declare the measure value field as Integer for Damerau-Levenshtein and Needleman-Wunsch (same as Levenshtein), matching the Long distance written at runtime and avoiding the Long vs String type error when storing execution data.

2026/08/07 22:25:14 - demo_fuzzymatch - measure value String : There was a data type error: the data type of java.lang.Long object [5] does not correspond to value meta [String] (through reference chain: org.apache.hop.execution.ExecutionData["rowsBinaryGzipBase64Encoded"])

• Simplify FuzzyMatchMeta (including Algorithm and FMLookupValue) with Lombok @Getter / @Setter.
• Add a unit test asserting distance algorithms expose an Integer measure field.
