feat(pinia-orm): add whereLike & orWhereLike query methods

[CodeDredd]

Feature (#1692)

Laravel-style whereLike / orWhereLike on query & repository:

useRepo(Project).whereLike('name', `%${query}%`).get()
useRepo(User).whereLike('name', 'John%', true).get() // case sensitive

• % matches any number of characters, _ exactly one — pattern is compiled to an anchored RegExp with all other characters escaped.
• Case insensitive by default, opt-in case sensitivity via third argument (same semantics as Laravel's whereLike).
• null/undefined field values never match.
• Non-string fields are stringified before matching (whereLike('age', '3%')).
• New docs page api/query/where-like.

Tests

7 new tests: contains/starts-with patterns, case sensitivity, _ wildcard, no-wildcard equality, orWhereLike, numeric fields. Full suite green.
