feat: add texture aliases

[Juknum]

Requirements:

• feat: add contributions support #2

Description:
Textures can have multiple names across multiple mods, some mods may not use the "right" way/convention to name their textures which can lead to contributors not finding their textures when selecting the texture to their contribution.

To do:

• keep a name field, set when the texture is first added to the database
• add an aliases field (string[]), where the texture already exist in the database but uploaded again (only add the name in the aliases array iff : different from name and not already in aliases
• update contribution draft modal to allow aliases search.
• remove hash from texture name in database, filepath already have it
