Exclude egld-000000 from tokens count response

[stefangutica]

Reasoning

• EGLD-000000 is a synthetic entry added manually to the tokens list (for multi-transfer support). It was filtered out only in getTokens, so GET /tokens/count returned a value 1 higher than the number of tokens actually listed by GET /tokens.

Proposed Changes

• Moved the EGLD-000000 exclusion from getTokens into getFilteredTokens, so every consumer of the filtered list (list, count, tokens for address) sees the same set of tokens.

How to test

• Compare GET /tokens/count with the number of items returned by GET /tokens?size=10000 — the values should match, and EGLD-000000 should not appear in the list.
• Repeat with filters applied (e.g. ?type=FungibleESDT, ?search=...) and check that list and count stay consistent.
