[16.0][l10n_br_fiscal][l10n_br_hr] fields.Text -> fields.Char where possible

[rvalyi]

convert fields.Text to fields.Char where it makes sense.

Feature	fields.Char	fields.Text
Max Length	256 chars (configurable with size)	Unlimited
Database Type	VARCHAR(size)	TEXT
Use Case	Short strings (names, codes, emails)	Long, multiline text (descriptions)
Supports Newlines	❌ No (single-line)	✅ Yes (\n works)
Performance	✅ Slightly faster (fixed-size)	⚠️ Slightly slower (variable-size)
Example	name = fields.Char(size=100)	notes = fields.Text()

Hi @renatonlima,
some modules you are maintaining are being modified, check this out!

Na verdade eu acabei de checar num banco de prod 14.0 e NCM e CEST tem name mais longos do que 256 chars (3x mais!) então parece que não poderiamos alterar para esses:

odoo14=> SELECT
    MAX(CHAR_LENGTH(name)) AS max_length,
    CASE
        WHEN MAX(CHAR_LENGTH(name)) <= 256 THEN 'Convertible to VARCHAR(256)'
        ELSE 'Cannot convert - exceeds 256 characters'
    END AS conversion_status
FROM l10n_br_fiscal_ncm;
 max_length |            conversion_status
------------+-----------------------------------------
       1159 | Cannot convert - exceeds 256 characters
(1 row)

odoo14=> SELECT
    MAX(CHAR_LENGTH(name)) AS max_length,
    CASE
        WHEN MAX(CHAR_LENGTH(name)) <= 256 THEN 'Convertible to VARCHAR(256)'
        ELSE 'Cannot convert - exceeds 256 characters'
    END AS conversion_status
FROM l10n_br_fiscal_cest;
 max_length |            conversion_status
------------+-----------------------------------------
        601 | Cannot convert - exceeds 256 characters
(1 row)

dessas mudanças que eu propois aqui, daria para reduzir aprenas para NBM ou icms_regulation. Vamos pensar melhor mas talvez não der para mudar no data_abstract mesmo, ou digamos que não valeria a pena.
