feat(building-comparison): add metadata table

[Gigaszi]

Metadata table created wiith this SQL query:

-- Create metadata table without coverage columns
CREATE TABLE comparison_indicators_metadata (
    dataset_name VARCHAR(255),
    dataset_name_snake_case VARCHAR(255),
    link VARCHAR(255),
    date DATE,
    description TEXT,
    color VARCHAR(50),
    table_name VARCHAR(50),
    coverage_simple GEOMETRY,
    coverage_inversed GEOMETRY,
    indicator VARCHAR(50)
);

-- Insert data for EUBUCCO dataset
INSERT INTO comparison_indicators_metadata (dataset_name, dataset_name_snake_case, link, date, description, color, table_name, coverage_simple, coverage_inversed, indicator)
VALUES (
